--Just found out Sailing is an olympic sport, lots of varieties. Turns out it first debuted at the olympics in 1900. So, I suppose its been around long enough to be considered a classic?
--Not sure what Trampoline was til just now. Watched a video. Exactly what you expect. I'd keep it in the olympics.
--BMX? WTF? Not everything needs to get a medal. Same goes for snowboard in winter games. Too "narly."
Frankly, I prefer the classics, and individual evetns vs. team sports, because the olympics should showcase overall athleticism such as decathlon
Side note the winter Biathlon seems pretty unique, you gotta be able to cross country ski and have precision rifle marksmanship. They ougghta just select two random sports as the "surprise" for every olympics where any ahtlete can sign up but wont know what the event is until a month in advance.
Such as:
1. Shooting/Sailing -- essentially olympic Pirates event
2. Swimming/greco-roman-wrestling -- first competitor to drown the other wins and lives
3. Archery/Boxing -- good training for zombie apocalypse
