Yes we did have problem with 1 neighbor. The city was involved as the polica also came out. It turned out that we where in no violation as far as the city was concerned. Because we started after 8 am and where done before 10pm. The track owner just decided to close it up just to keep the neighbors happy. He figured it just wsn't worth the BS for a few races a year at his house. So my suggestion is to first talkto your neighbors and your city zoning dept. If all else fails get the neighbors to buy some rc vehicles and ask them to play with you.
