Question for skateboarders and bike riders?

Hello men, I have been thinking of this for a while and would like some answers.

I am a girl and am getting into Bike riding like Flatlanding and Jumping in Skateparks =) My sister is a Skateboarder even though she doesn't admit to it, haha.
I was...

just curious what you think or how you react if you came upon a female skateboarder or bike rider at a skatepark? Would you really expect them to do crazy tricks or just assume like, Oh, they're girls they can't do Anything! and then laugh it off.
Would you guys laugh at me if I were to ride in (as a beginner of course) and practice in front of a bunch of guys?
BECAUSE I ask this question, My sister and I are not very confident and worry what guys might think.

THNKS A TON!

I wouldn't expect em to do any tricks. I'd think its cool that a girl is learning to skateboard! Thats really all. lol

Skater/biker nubies are usually met with kudos, I mean your giving it ago, so I say go for it they will be more likely to help you guys out give you tips etc. than to laugh at you, skater folks are usually decent people and hell they'd most probably liek the fact that two girls were down the skate park for once...
