Wooded trails in Staten Island that are great in the winter but overgrown in the summer. These trails are not worth traveling to, BUT if you live close enough to ride there, why not. Winter is the best time for these trails. My favorite time to ride here is a few days after a snow fall when the sun softens it up but the ground is still white.
