Yippie - we are going to Frederickburg, TX. for my birthday! Only for one night - but I am so excited. I used to vacation here with my parents and I love it. Very close to Fredericksburg is a great place to hike called Enchanted Rock.
The Indians believed that Enchanted Rock was a mystical & spiritual place because it would often make cracking noises..
..the noises they heard was the rock expanding and contracting with the temperature changes though.
