Allen Plano Richardson are not the places to be if you want a shorter commute. Desoto is a much easier commute, but I would suspect the reasons for the move is due to the schools. Anywhere south is going to be easier to travel than those to the north of downtown. It takes me about 40 minutes to get from Allen to Desoto in the morning at 6:00 am. It takes at least a good 1:15 to get back home if traffic is playing nice on 75 at 4:00 pm.
