Can you believe that we've just seen the decade's final major championship come and go?
Doesn't it seem like just yesterday that Phil Mickelson hit that incredible mid-iron around the tree on 13 at Augusta en route to his third green jacket at the 2010 Masters?
But just like that, we've closed the book on an entire decade's worth of major championship golf, bookended by decisive, popular victories.
Here are four takeaways from The Open: one big positive and a few episodes that are perfect 19th-hole debate fodder:
Portrush is prime future Open territory
For nearly 70 years, Scotland and England have hogged the spotlight that comes with hosting The Open. Most American golfers had no idea how beautiful and great the links in Ireland and Northern Ireland are until watching Irishman Shane Lowry win this weekend.
Praise for the Dunluce Links at Royal Portrush and the tournament was universal from fans and R&A officials to players. It was the first sellout in Open history. The Irish love their golf; without a doubt, this was the biggest sporting event ever held on the Emerald Isle.
The links might have already leapfrogged more established Open venues to become one of the more popular stops on the rota. It's fair - you'll note that none of the good shots down the fairway kicked into bad lies in the dunes like other links - and scenic and challenging. The fact that traditional Irish weather, wind and rain, affected play during the final round added another element of intrigue, even if Lowry ran away with it.
Portrush has already proven it deserves a return trip, and likely several more. The BBC reports that The Open could return to Portrush as soon as 2024.
"If we have to wait another 10 years, the icing might rub off between now and then and people might forget," Graeme McDowell told the BBC. "Hopefully we can get it back soon - it would be very special."
Slow play rankles Koepka and fans
Though he began the final round with already-minimal opportunity to win, given he was seven shots behind Lowry, Brooks Koepka's playing partner did him no favors. First-round leader J.B. Holmes is notorious for his slow play, and Koepka, one of the PGA Tour's fastest players, made his displeasure with Holmes deliberateness known in subtle but stern ways on Sunday.

The fact that Holmes shot 87, the worst score of the weekend by 7 shots, did not help matters.
Pace of play is a constant source of complaint for golfers in all situations - not just elite competition. Even long-tenured rules officials have balked at the idea of enforcing penalties for slow play, owing to the amount of money players stand to make. It is clear that pro golf is not going to solve the game's pace of play problem anytime soon. We amateurs, and the facilities where we play, are going to have to do it ourselves.
A four-letter word we actually want to hear
Young Scottish pro Robert MacIntyre had an excellent debut at The Open, finishing tied for 6th after a final-round 68. Though he never really challeged for the claret jug during the week, he played a significant supporting role to the week's proceedings when, after Friday's round, he called out American playing partner Kyle Stanley neglecting to yell "Fore!" on two separate occasions of Stanley's wayward shots: the first, on the 14th hole, when his ball struck a marshal in the crowd; and on the 17th hole, when his ball struck the mother of MacIntyre's caddie.
Yelling "Fore!" anytime your shot might endanger somebody is so fundamental to the etiquette of the game that it tends to be one of the two or things that people who have no interest whatsoever in golf know about the game. A professional golfer, who plays among spectators dozens of times per year should be able to do it by instinct. And on links courses, where choppy terrain can create blind spots, this common courtesy is especially important.
Not only is this common courtesy, it's a potential matter of liability which such bodies as the New Jersey Supreme Court have pondered. Note to Kyle: when in doubt, shout it out.
2016 Open Champion Henrik Stenson has a well-deserved reputation as one of the great iron players of his generation. Which made the utter shank he hit on Sunday all the more perplexing. The statuesque Swede has both one of golf's best senses of humor and one of its quickest tempers. You can probably guess which one surfaced at Portrush.
