I went to one of the state schools on this thread and graduated in 3 years, with only 1 incoming AP credit. The availability of summer classes was outstanding, which is how I was able to do it. Most students (including me) were not wealthy and had jobs. That’s why they take lighter loads, as noted upthread.
I agree with the Utah suggestion. It’s quite sunny and really can’t be beat for outdoors stuff.
