how much farther? rausch creek is in pa. there are rocks and mud there (predominantly rocks, but there are some nice mud holes too). also, the pine barrens in south jersey, lots of mud and water. there are 2 brothers from boston that come to the pine barrens jamboree every year. the catskill mountains in monticello, ny are a good spot for rocks and mud. killington, vt has sweet trails.
