This cache is available to both north and southbound traffic How many times have we stopped here after a trip up north. Always amazed that there wasn't a cache here. This is a very nice service area along I35 that supplies food, gas, and a place to just stop and rest your eyes if you're tired. If heading south the next service area on the interstate will be in Oklahoma so maybe you need to stop and grab that coffee here....oh and grab the cache! Should be an easy P&G. Save travels!
