LOTO boat 7 mos. out of year and plenty of construction. Huge beautiful lake with lots to do on the water, bars, restaurants... Slow during winter though.
I've heard that Austin is a great city with a lot of culture. Longer boating season also. I would imagine a city of that size would have plenty of construction going on and demand for plumbing. Not sure about the cost of living in Austin.
Ever thought about Lake Havasu City, AZ or West coast?
Springfield, MO is a decent sized city near Table Rock lake and a few hours from LOTO. Branson, MO is booming too and your right next to Table Rock. Cost of living in MO I would bet is much more comfortable that South FL.
