I am taking 3 of my girlfriends to Texas in May - one of them has never been there before. We will start in Austin where I have family, and a brother has offered us use of his ranch in Llano for a few nights. I have never been in that area - what should we plan to do? eat? Is it close to any national or state parks? Evening entertainment? We are 4 women in our 50s who have known each other since the 70's.
