Yeah that was weird - taking red from white towards canal road, at the next to the last smaller roller all these flags are around the trail and I thought more new trail was being mapped out. But instead there's a clearing going down to the creek - looks like drainage of some sort.
PS with the new trail extension on blue I created a new strava full loop segment from canal road - blue, red, orange, red to 27 lot, back to orange, red, white, red to canal road. Since only three people have ridden it so far - I'm number 3 - yay me. Alex K is KOM at the moment
