Skateboarding when it rains is pretty difficult. Not only is it really slippery (so quite unsafe), but also skating with rain-protective clothing is kinda restrictive, so your choices are skate while feeling uncomfortable, or get wet!
But if you live near an indoor skate park, then the rain can't stop you from skating.
And if your local shopping mall doesn't mind skaters, then that would be even cooler because you could hang out with people too, but NO WAY would the mall guards let you skate indoors (even though in the Tony Hawkes game it has levels where you can.. how unrealistic is that?)
And these days, it seems like everybody hates skaters.
Have you seen the report where heavy metal singer Rob Zombie complained about kids making noise in a skatepark near his house?
I mean, come on! This guy is a heavy metal singer for Pete's sake!
