I went for a road ride yesterday and stopped by the Canal Road lot to use the porta-john. The lot was full. Interestingly, there was only 1 bike rack in the lot and the bike was still on the car. The owner was checking out the trail map and we ended up chatting for a few minutes. Turns out it was his first time there. He told me he actually walked out on blue for a bit and that it was seemingly dry. He was wondering if the "too muddy" signs were legit. I explained that they were. He had a really good attitude and actually got back in his car and left.
When I was leaving the lot I did see several, what I will describe as non-cyclists (no helmets, sneakers, old poorly maintained bikes) trying to figure out where the trailhead was. This "user group" truly has no clue. With everything being shut down due to the Coronavirus outbreak people are coming outside. Every park I rode past or through yesterday was packed. I haven't seen so many people enjoying the outdoors in a long time.
TLDR:
It seems that hikers don't think the trail closure applies to them.
"Cyclists" seem to be staying away.
Coronavirus has driven the masses into the outdoors which may be the silver lining of the whole thing.
