Thanks for the answers. We're both high school seniors (I'm 18, she's 17) by the way. I feel like she'd prefer skating cause she's a pretty outgoing, energetic person but im not sure if it'd be too difficult to have a conversation.
But if she is not a skater, you have the advantage of helping her. That's a great strategy that could work in your favor. I've always been a skater so I don't have first hand experience, but I've watched one of my friends with a date while they were skating and I kept thinking "he's scoring points here" with him having an excuse to touch or hold her, and her having to hold onto him and all that good stuff.
I have heard, though, of a bad experience someone had. I think some people are just truly terrified of skates. I would guess that is exceptionally rare, though.
