Hey Nighthawk - Welcome (potentially) to the desert Southwest!
I've been living here for just over 20 years, having moved from Anchorage, Alaska. On some days, I feel like I have not moved far enough south. In a couple of months I will feel like I moved TOO far south. My personal limit for riding in the heat is 105 so I don't ride much in the summer other than to find cooler clime's.
Actually, my personal goal is to move to Florida

I, too, live in the Phoenix area so no idea of the job market in Tucson. The job market in Phoenix is not that great as I know a number of people who have been out of work for some time. But, most have found other work. I lost my job a couple of years ago, but, since I am turning 65 in 2 months, I think it's been more an issue of my age than lack of work.
As far as riding, it just doesn't get much better than this. For me, a solid 9 months of riding, and the 3 months during the "monsoon" season I will get in a couple of rides just to escape the heat and humidity. And, yes, we do get humidity with dew points on occasion approaching those you are familiar with in Florida, but, add 30 degrees to the air temps.
Lots and lots of great riding in this area, almost too many to mention. As mentioned - Mt. Lemon and AZ Bike Week. But, there is so much more. You have Kitt Peak, home of some 25 optical & radio telescopes, a few which you can even tour just a short ride from Tucson. A little further up the road is Flagstaff, which is popular to get out of the heat where one may visit the Lowell Observatory. Tucson is surrounded by the Saguaro National Park, which is made up of two parks on either side of the city and is a fun place to ride. Just on the west side of the park is Old Tucson movie studio and theme park where a lot of the old westerns were shot. Davis Monthan AFB is located there where the USAF stores its older aircraft out in the desert. Based on aircraft inventory, Davis Monthan is the second largest AF in the world, of course most are not airworthy. There is Organ Pipe National Park which is also a nice day ride. Not only is there the AZ Bike Week, but, we have the Laughlin River Run, which is billed as the largest bike gathering in the West. Think of a mini Sturgis, if you are into that sort of thing, at the end of April. There are a number of old mining towns where one can ride and tour. To the east of Tucson is Kartchner Caverns and Colossal Cave, both an easy ride to allow tours of the caves. Northeast of Tucson is the Biosphere 2 science research facility which is an amazing place to spend a few hours after an easy ride.
Not to mention hundreds and hundreds of miles of open road out in the desert.
This barely scratches the surface of fun places to ride.
Hope we can share some road some day!
