what is the reason the trail is off limits to bicycles? will a bicycle hurt/endanger/ruin flora, fauna, ecosystem? or is it because people don't want bicycles racing around on their trails?

as long as no harm is being done, there is no reason to not ride a bike somewhere if you aren't endangering or bothering others.

i also run red lights at intersections AFTER i've stopped and seen that i am the only person sitting there at a 4 way, waiting for the light to change. i also turn left at right turn only places as long as i'm not causing any traffic chaos or affecting anyone else.

i'm not going to blindly follow rules or signs or marks on the road just because they are there. we are cognitive reasoning beings, we should act appropriately according to the situation.

the only difference between "riding" and "poaching" is an inanimate metal sign. all other conditions are the same.

if a trail is "off limits" because they don't want cyclists bothering other users, i will ride it when no one is around, because there is no real actual valid reason not to ride it.
