Ain't neighbors great? The 2 brothers covered in the original post, years ago after a hurricane came through, helped the very neighbor that made the complaints, clear trees from the neighbor's house/yard. How soon people forget who their friends are.
Most of my neighbors have made compliments on the MVs in my backyard, and said "they'll know where to go when the next hurricane hits". While it's uncomfortable for people to say they'll make use of other people's preperations, it's nice to know that the neighbors that made those statements at least can see a use for such vehicles.
An update on the two brothers. The codes listed on the friendly city hall letter do not refer to vehicle regulations for private use. The codes refer to commercial use only. It's beginning to sound like someone at CH made an assumption.
Power to the people, and all that.
