Thanks everyone for your replies. I was in AZ 30 years ago & know what the weather is. I may go there sometime, but think FL for Feb and MArch is good for me. I enjoyed it 2 years ago although they had a week of record highs which were a bit hotter than I like. I'll probably visit 2 cousins in Lantana & Ft Lauderdale, then go to the Keys were a buddy should let me park for a week and might have a chance to go out on his boat. Then to the everglades again to stay for a week or two just for the warmth and isolation, then on to the SE corner of Tampa bay for a couple weeks. I saw 2 spring training games 2 years ago & hope to see more. I may try to charter a boat for a few half days on the Atlantic side targeting wahoo, dolphin, king mackerel, etc.
This is not expensive as the Senior pass gets me half off in the glades camp and the camp nearer to Tampa gives senior discounts too.
