No black flies.
It's this huge equestrian center that I think owned by the county, the same entity that owns the miles of gravel trails and limited amount of single track near my house.
There's technically a bike path in the center but it doesn't go all the way through. And yea, you do come to a point where a sign says "no bikes beyond this point."
It's a crucial connection for me, it connects our woods with the rest of the system. The first few times I got off and walked it. Eventually I started riding, slowly along the edge of the woods.
The horses are in huge corrals (do they call them that?) I've rarely been closer than 50 yards from a horse, except occasionally they'd get curious and walk over to me. Sometimes the horse are giving lessons. Usually they are just chilling but lately they are running a lot. They don't seem unhappy to me, maybe they are flirting.
Today I actually came across a lesson on the bike path. There are signs all around that show that bikes and walkers yielding to horses. I dismounted, they said thank you, and walked by.
Nothing is beats strapping a couple of boards on your feet to go down a mountain, unless it's getting on a thousand pound prey animal with a mind of its own.
