I'm headed for the hill country in early April- can't wait to see the wildflowers. Will also visit Austin, SanAntonio, Kerrville, Fredericksburg,-- and whatever else y'all recommend. I'm especially interested in advice for a gal with a little airplane: Where to land, where to stay, what not to miss, what adventures to have. Particularly interested in things a little off the beaten path, discoveries that will lend a feel for the REAL Texas. Thanks!
