I believe Sam was the one that told me why the town seemed to have so many used AR's(and other assorted assault rifles)---but all the shops seemed to have more than the typical amount for a town that size. There was an unusually high amount of other mil-surps I observed in the shops, and I was told because of the amount of retirees that they sometimes get whole collections at a time. They told me that at the shop I can't recall the name of (maybe Southwest firearms?) when I walked in and there were 30-some Lee-Enfields leaning against the wall, all in VG-exc. with bayo's and slings and I asked what distributor they cleaned out of handpicks---he said we get widows/families in here often selling off the guns of a guy that recently died.
Anyways, We came very close to moving there about a year ago, so over several trips we investigated all the positives---good gun stores, surrounded by BLM land everwhere with good 4x4 trails and shooting, good food (along with Laughlin), fairly limited growth (compared to Tuc., Phx.), pretty much all services available without travelling. Oh yea, the RIVER. These all outweighed the negative (the HEAT) by far. Something else fell thru, so it got cancelled
In my original post, when I used the word 'there'---I mean Lake Havasu, not one particular shop
