Colter Bay (Grand Tetons) to Massacre Rocks SP (Idaho)

Just wanted to update for those that may follow: We took the Hobeck -> Alpine Junction as planned, and it was a very easy and scenic ride. After a stop at the Pocatello Walmart during what had to be one of the most intense rainstorms I've experienced in a LONG time, we made our way to Massacre Rocks at about 4:30pm last night and enjoyed and evening and day here - it's a great park - we really recommend it. Tommorrow, onto Winnemucca and then home (Fairfield, CA) early the next day. Thanks!
