I feel your pain on this..  as well as with the stupid people (I am thinking of some stonger language) who don't care about rules.  I have a small track on my property for us but some local idiots ride there & then go tear up a cotton field... leaving tracks right to my place.  At least I have a distinctive cheapo tread pattern on my tire for now....
 What you're doing is GREAT and I'm coming for a membership (me, my fiance at least but also my neighbor, my friend, and anyone else I can find) as soon as I can as long as you're still open.  Really want to try riding on the tracks but I usually look for trails and the couple videos I've seen of yours show some fantastic ones. 
 You want I should bring some weapons as gifts for you?   :D 
 Maybe accidentally turn these guys/girls into KX500 roost?
