1st, 10 uears may be optmistic for time spent at the regionals. As for states to fight instruct, I would say Florida is the top choice thanks to good flying weather and a load of 141 flight schools that are pretty busy. Next choice wold be california, again because of lotd of foreign flight students and good flying weather. Third choice would be TX, but choose a good city like Dallas or Houson where the student numbers are high.
