I agree that rollerskater girls are cool and I have no issue with them, but I'll throw out the unpopular opinion about them.
I see some of them doing grinds on lower boxes where they put one skate up on the ledge and their other leg is still on the ground, then they lift up the other skate into the grind never having jumped into it. Maybe it's a way to learn, but the ones who do it easily enough AND for an entire session don't get a pass that's illegal. Jump into it.
