Jeff Slavens, of Slavens racing, has been around and involved with Colorado trails for more years that I've been alive. Below is an excerpt of his latest email to customers (worth subscribing to, it has tech tips and etc in addition to hawking his wares). I think it's important reading, especially for folks who are considering making the trip here. These same thoughts very much apply whether you are on trail or passes and fire-roads. Last year, we had a few bad situations with out-of-staters coming to CO, going off-trail to get around snowbanks and obstacles, and creating real problems for the local clubs trying to maintain access to the trails we all love. If you are coming to visit, welcome, and please keep these ideas in mind. If you live here, they are still relevant, and if you know someone coming to visit, maybe forward this along.
