When entering the Pines, head left first and follow the orange/green markings the best you can. The first mile or so is very muddy with log bridges and stone pathways. Entering the field area, follow the orange tags on the trees to find the entry back (just before the NY state line) into the pine tree portion.
The trail was muddy when I rode - the beginning of July. No rain at least four days prior. I get the sense this area always has muddy spots, regardless of time of the season.
