It wouldn’t be so bad, except that they’re entirely blocking a walking path. It wasn’t such a problem for me, but considering where it’s parked, they’ve prevented anyone with a disability from using that path since even I had to go off it into the snow to get around.
They obviously weren’t loading or unloading - the bed of the truck was AWAY from any buildings nearby. I assume it was just plain easier to drive up a path then to park it in a parking lot (there was one at the bottom of that hill! Just a few dozen feet away!).
