+1 to what Beth said.

If you want to get even more involved, you might offer to help come up with actual rules for the path, that would then be enforceable. Obviously if there are no rules there can be no tickets, but I don't necessarily think that having rules is a bad idea.

Some of the MUPs in my area have a posted 15 mph speed limit and I really don't think that's unreasonable. (Cyclists who want to go faster belong on the road, and the ones who are using the path to access a road can just chill until they get there.) A center line (if there isn't already one), keep right except to pass. Wheeled vehicles including strollers, single file except when passing. Pets on leashes not exceeding 4 feet in length. Audible signal when passing. Person being passed must yield to the right. Children under 10 must be accompanied by a responsible adult. And so on.
