Most likely will be coming to visit family in Oregon next year for Christmas. Want to bring sleds. Was wondering if there is any training and or certifications that i need. I know you need training for ohv, does this apply to snowmobiles as well?? If so where can i find info and is there any online courses I can take?? do I need Oregon registration or will they honor Colorado tags?? will be in Eugene area and riding around Hoodoo, Batchelor, and Willamette Pass. Any info would be great!! THANKS
