I have nowhere to skate

The nearest roller rink to me is about a 5 hour drive, and there's nowhere to skate indoors. I live somewhere that gets very cold and snowy in the winter. I really, really want to keep skating- I started about a month ago and I've been having so much fun. I've been skating on tennis courts, but every time I go, I get looks if there's anyone there, and I was asked to leave once. My city is very unwalkable, so sidewalks aren't an option. I'm terrified of being kicked out for good from the courts- I'm a teenager and that puts a bigger target on me, since I'm not only seen as someone breaking tennis court rules, I'm also a "loitering teen". I looked it up to try and see if skates actually damage tennis courts and I couldn't find any actual, measurable evidence, so I don't know what I'm supposed to think. Our only skate park is on the bad side of town. Is that my only option? Where do you folks with hostile cities skate?
