Once at the river, I did take the paved roads over for about a mile or so to a park in Buxton along the river. Road some of the trails there, then sought some different trails on the way back home.
Hit paved road for a few hundred yards up a hill to go an area where I thought some snowmobile trails might lead me back to the abandoned railroad bed. At the top, I stopped to talk to a guy working on his yard. He also bikes and we chit chatted for about 5-10 minutes and he tipped me off on what the trails were like ahead. His advice was great, as I successfully found the connection back to the railroad bed and back home.
What remains of where the abandoned railroad used to cross the river.
