Heading to the Snowies Valentines weekend and will be coming late Thursday night. Staying at Old Corral and just checking to see if we can buy the trail permits in Centennial or do we need to stop somewhere in Laramie to pick them up on the way through????? We will be hopefully pulling in Laramie around midnight....so any place open that hour if we cannot get them in Centennial???????? Also any advise on parking @ greenrock and do we need a permit to park? Thanks for the info in advance!!!!!:face-icon-small-ton
