hi
The Mrs and I really want to tour outside europe in July - usa or canada perhaps given three weeks isnt actually that long.... Flight costs are not important as its my only holiday all year and want to throw the credit card at it.. It needs to be a challenge and in mountains...we are both fit road racers who fancy something different. Can be on/off road. Really appreciate the advise. Saw one post about Vancouver to Calgary..any good ...or just crazy traffic jams with the tourists? We have ultra light tents and sleeping bags from mountaining trips so expect to sleep as need to rather than have to be anywhere specific for a hotel etc
Thanks a lot
