I love to travel, so the county doesnt matter.... How about narrowing it down to the funnest cache you have ever done in Texas, not extremely difficult, could be done with a group of cachers, and has something of historical value or a landmark, such as a park or significant object around the area of the cache. This way, I could cache and learn something about the area in the process. Since I am a new cacher, it doesnt need to be extremely far away from the starting point, like hiking Guadelupe Peak, and taking hours to find since I am not very good at caching yet.
