You can't really tell from this picture, but Alex Rodriguez and his girlfriend ARE technically mountain biking!
Sure, there isn't a mountain — and it looks like a flat residential street — but they are riding mountain bikes.
Who are you to define what mountain biking is anyway?? They're just out getting fresh air and exercise! Don't taint it with your ridiculous demands!
We wonder if they found any sweet jumps later!
