I have found a map of the Canyon Lake area online that will orient you a bit better if you are interested. Jim and I are camped out on the end of the peninsula marked with the boxed numbers 18 and 19, which are boat ramps. You can also see the relative location of Sattler and a few other burgs on this map.
I like this map even better. After you look around on the map, click on "Satellite." You can then zoom in on the satellite photo. If you will give me some advance warning of when you are going to do that, I will wave at you.
Kindly do not pass this information along to the process servers.
