I would only go here if you live with in biking distance otherwise it's not worth it.
On C-470 take the Ken Carl exit and continue on Ken Carl Until Garrison make a right and make a left on <br /><br />Fairview Ave (the first left after the car wash) and you'll see a Field on the left side of the road.
