Planning on heading out West in late July or early Sept depending on feedback. Looking for tips on routes. My initial thought is to head north out of Boston on 93N to 89N and do the trans-canadian out to Thunder Bay at least, then drop down into the US for 2 reasons, congestion and heat. After that it west through the Plains and into the northern Rockies to the west coast. My plan is to slab it for the 1st part to make time but after Thunder Bay I welcome local knowledge for routing west on secondary roads (not a big highway guy). Im riding a BMW R 1200RT so gravel is out. Thanks for your input.
