You are walking along the Marshal Swamp Trail. A bit over a mile long, this trail twists and turns through some great landscape. There will be ticks and occasionally mosquitos. Even though this is a great trail for walking or biking, it can become muddy at times. You are searching for a unique cache that should be tethered in a location that should be pretty easy to spot.
