Every year around this time, I look at all that's going on across the pond. If you do a month give or take in Western Europe from mid June to mid July, you could conceivably see all this:
French Open (tennis), May 22- June 11
24 Hours of le Mans, June 17-18
Wimbledon, June 25- July 15
Tour de France, July 1-23
Running of the Bulls, July 6-14
The Open Championship (golf), July 20-23
And I guess if you have the time and are into that sort of thing, you could even take in a Communist Kickball game or two.
Now don't get me wrong, our team games that are popular here will always be my first love, but I can see them anytime. Take this trip, and you get to see a bunch of sports that you don't often get to see in person, at least at the highest level.
