Homestead Heritage is a wonderful place to visit and it is free. The have a working griss mill, pottery and blacksmith, a barn with things they sell. They have a resturant and bakery. It is like stepping back in time. It is in Elm Mott, just past Waco, so about 1.5 hours from Ft Worth.
Tyler texas is beautful this time of year, now it is a bit over 2 hours accourding to Google maps, (136 mi – about 2 hours 16 mins) but the Rose gardnes are fabulous and the tour of the Museum is fun.
