I'm in the northwest suburbs too. I just got a P4. Some say you can fly at Busse woods, but the sign says you need to be a member of the Association of Model Airplane something. Is that a problem? Do you have to join? Seemed like a good place to fly. I'm FAA Registered, but nervous about having people get upset with me.. I've only flown once and very briefly. I just got it last Thursday. Sounds like there's lots of folks in the Northwest suburbs.
