We spent the month of February at The Palms in Yuma. Really, really nice RV resort. Gated, 24 hour security, 2 pools, 2 spas, activities, grass dog park, friendly staff and guests, $33 night (monthly rate + electricity), well maintained grounds, sites are plenty big. Family RV did a residential frig install for us. David was great to work with 928-304-9672. Can't help with the other two questions. Meyer Optical in Los Algodones did glasses for the wifey. Eat at La Fonda Tortilla Factory at Charos. Visit Territorial Prison Museum and Quartermaster Colorado Crossing Museum. Skip the swap meets.
