First of all, stosh has talked to these guys several times. The FIRST conversation should be warning enough.I know atv riders are bad people and all, but can you explain why 5 days a year of minor nuisance is cause for maiming?
We have all poached trails. I try to do it respectfully and discreetly but maybe they just need a little education on that front. If erosion on the streambank is your beef, maybe post a note asking them not to spin their tires up the side.
I don't poach on private property. There was a similar connector trail in Baton Rouge that changed ownership. The new owners told all the riders to beat it, and I've haven ridden that trail since.
