Hi Sally - my kids and grandkids spent a couple of nights in Huntsville, a few years ago, and went to the Space (museum?) thing there. They talk about going back, but so far haven't gotten brave enough to try to put the 3-year-old in a car for that amount of time.
We go to Nashville sometimes for a weekend getaway, there seems to be more to do there than here in Memphis. But maybe it's because we are used to everything here, and somebody from out of town wouldn't be. If you see you are going to get here, send me a PM or an email and maybe we can meet for coffee or something.
