First ride back at 6 Mile since hip surgery in February. Coming from Canal Rd on Blue riding thru the fields, we noticed there was an offshoot trail to our right running thru the woods parallel to the field. Then where the trail goes left, the old trail is blocked and there's a new trail thru the woods again running somewhat parallel to the old trail. When we popped out of that, we noticed the old field trail was not blocked off at the opposite end (looked like maybe it had been blocked because we saw debris laying alongside the trail). Are we supposed to be using (only) these new trails now?
