This cache is one in a series of caches designed for beginners - they are placed mostly at the fitness stations along the walking/biking loop. This one is not at the fitness station, but is just up the hill a bit. I recently replaced this with a new cache type which might be more difficult for beginner cachers to find so I upgraded the difficulty to a 3.5
You are looking for something that fits in, but doesn't quite fit in. Please be gentle with this one as you retrieve and replace the cache.
