Regarding Quartzsite:
We were there for our first time in January 2008. Stayed in the amateur radio area. Nice people, interesting forums. Took a lot of pictures. Ate great Mexican food (a new standard in excellence) in Parker, AZ, which is a few miles north of Q. Traveled up to Lake Havasu City from Parker; scenery is spectacular. We stayed in Q area for only 5 nights. We then retreated to civilization in Buckeye, AZ where there is a very comfortable RV park very near a SuperCenter and a Fry's grocery. If we were to go back to Q (and we just may) we would stay on the north side of town so we could more easily go back to Parker to have great Mexican fare, but we would look into renting a site for a two or three month stay at the Buckeye RV park, then come and go as we wish, perhaps boondocking a week or two, then return to "civilization". It is a great place to enjoy the winter.
