I dont know if the adventure pass in oregon is the same for Glamis..There are a few lil places like mom and pop marts that advertise the passes right in front of theire store.They were 22 bucks for the 5 day pass or 100 for the year,Registration must be on you now because of so many hot bikes,Non registerd with a dummy tag and so on.the passes are just for your vehicles,none needed just for the bikes..You can also buy the passes online at american sand association,sand addiction magazine,and a few other places..Just google glamis passes and see what pops up..
