Where to find a lot to practice in?

Hey, where do you all find big, smooth parking lots to practice in, and not get thrown out?I tried an office park near here, but it was still full of cars at 7pm. I don't think the people in the houses will appreciate me revving and ripping around in lots near them, and I'd like to avoid encounters with cops if possible. via /r/motorcycles https://www.reddit.com/r/motorcycles/comments/d9kv2r/where_to_find_a_lot_to_practice_in/?utm_source=ifttt
