congrats! talk to the leasing office and ask if you can authorize your dad to do the key pick-up (my oldest's place has an authorization on file to let me do things-just a simple signed paper we put together prior to move-in). also make sure you've got renter's insurance that covers everything you need during the move period (old place through whatever date you are legally obligated/new place from date you are obligated/personal property during the time it will be transported).
I will be interested to see what you think of the Texas vs. California heat. knew people from Texas that swore California's dry heat was much worse but then some moved TO California and after a year or two found visiting family back home in Texas intolerable b/c they were dry heat converts
