Our neighbors on each side are in their 70's,great people,they get a kick out of it! Since Im always working on cars,quads,bikes,etc,we have an 8pm rule. No loud air tools,no test and tune,it helps keep a good balance between us all.
8pm, that sucks man, my neighbors are cool with it all. 10pm cut off unless I was getting ready for race and I had to tune, they new why I was doing it, but other than that I wouldn't do anything after 10pm if it me t starting the bike up. All other stuff they didn't care, because I was working in the trailer and I wasnt usually load.
