One thing I think I'm pretty good at is skateboarding. Just because I'm a girl guys always assume that I can't or that I suck at it, but it's one of my favorite things to do in my free time.
I skate to work on the board walk and street all the time, I can go off curbs and drop in. No one believes me until they see me ride and I always get a lot of stares or yells because not to many girls skate.
I think skating is great and it's great exercise, it's starting to dye out though compared to scooters and bikes. More people really need to go out and skate more.
