I think ROC was just stating something that I and I am sure many people assumed. Trust me, assuming is not a good thing but we all do it a lot. This post does not apply directly to me as I am 42, but I do enjoy introducing snowmobiling to others and that will apply to me and friends in the future. I "assumed" that if you were over 18 you did not need the safety cert, my mistake. If the people that were stopped with thier parents were follwoing the rules of the trail, using common sense and respectfull to the officers I think a warning would have been in order. I think we have learned a lot about the issue now and should move forward. I respect the DNR and the law and play by the rules, it is really pretty simple. I just guess we all need to read what they send us with our registration and maybe they can do a some more to let us all know. Looking forward to getting on the sled soon. Best regards to all, LD
