Only reason trails have been closed is ground condition. Ground not frozen or no snow cover.
The trail use to run a short distance on land south of me. That land was sold and the owners hated any off off road activity. The local club came and talked with me about cutting through a small corner. When we went out and look it made more sense (safety) to change the route a bit and run them across my land at an angle. They loved it, gave them a place to open the sleds up. To this day never an issue with the riders.
My agreement with them is simple soon as the corn is off go for it and of course when the snow is gone.
Q . Are there official dates on which trails open and close?A . Trail openings and closings are determined at the county level. Land owner easements usually dictate the earliest and latest the trails can open and close. Normally, these easements run from December 1st through March 31st. Each county usually has a “trail hotline” number that provides the most recent status of their trails.Q . I know I can ride the ditch, 10 feet from a county or state
