I wonder what's got her so annoyed in the first panel. Perhaps her friends aren't moving fast enough for her tastes, or they want to do stuff she finds boring. The "sled style" downhill racing looks like a ton of fun, and that excited smile is absolutely adorable. Yikes on her flip, but she's made of tough stuff and will be okay. A few spills won't stop her or even slow her down. Great intensity on her skid stop, and finally it's just a lot of fun to see her just flying along and doing the classic tricks.
