Pulga is the Spanish word for flea. They are small, black, and stick like a magnet. There may be some walking through tall grass for this one, so watch your step. This cache is part of a series in North Central Park, which is a fairly new park in Laredo. There are always walkers, joggers, and bicycle riders in the park. The caches in this series are all micro caches, being magnetic key holders, magnetic nano caches, and plastic film canisters. None of the caches in this series are in the bushes or trees, though some caches placed by others in the past are in these locations. Some are in the park itself, but a few are just outside the park. I live about a mile from the closest cache, so I will get my exercise every time one of these is reported missing. Be aware that you might get your feet wet for a couple of the caches, especially if it has rained recently.
