My family visited Lake Optima in March 2009. We didn’t plan the trip; instead, we went to see relatives in the Texas Panhandle, and while there, we hit geocaching.com and a couple of letterboxing sites to see what we could do for fun up there.
There were a couple in Texas, but the biggest clump of geocaches was located north, in Lake Optima. I was intrigued, since I’d never heard of Lake Optima. My brother-in-law said that it was a failed lake, and had never reached capacity. Sounded interesting, so the next day we packed a lunch, four adults and seven children into two vehicles and headed up the highway.
