as our Washington Backcountry Discovery Route map is just about to be shipped http://www.wabdr.com/ http://www.butlermaps.com/Motorcycle-Road-Maps/ i've been thinking about the TAT and CDR and how a nice N.W. adv route loop could be had. basicly it looks like this -Start in colorado/northern n.m. and ride the TAT http://www.transamtrail.com/ west to oregon. -ride north http://www.oohva.org/Back Country/BCDRmain.html and pick up WABDR http://www.wabdr.com/ to the canadian border -ride east (see .gpx links below) to the northern teminus of the TAT http://www.dirtbikemagazine.com/ME2...0&tier=3&nid=B3F3AA11B3314B538127448E5D45EFD5 and ride south back to where you started in colorado. of course there are some pieces from the western end of the TAT up to the start of the WABDR and then then again on to the northern end start of the CDR, but this is not a big deal and someone eventually will create those pieces (Oregon Backcountry Discovery Route - OBDR & Northern Washington, Idaho & Montana Backcountry Discovery Route - NWIMBDR). maybe the oregon section up north could just be enjoy costal riding time & the beach.
