There seem to be hand fulls of people in most large cities that have tanks, i advertise our San Diego club at the local hobby shop which also sells taigen tanks. Ive found a few guys that have gotten in further going IR conversion. They tend to casuallly show up to a battle or two a year.
this last weekend we had a battle that lasted about an hour with just 4 people screwing around for fun as the rest of the groupies seemed to be otherwise engaged in activities.
