Please allow scooters on the trail, but prohibit parking them there as a compromise.
I use a scooter instead of a car for a commute. I feel that it's clearly a beneficial alternative, for me and others who want to do the same. I understand that parking them on the trail can be disruptive, but when actually using them, any concern about them is no different than a bike. Both can go too fast, both are up to the rider to use responsibly. I would argue that scooters also take up much less space than bikes, strollers, or dogs who sporadically veer left and right as far as their leash allows.
