There is nothing worthwhile seeing in Canada other than British Columbia,Nova Scotia and Quebec anyway Alberta maybe, just to see the Rockies
The rest is sorta like a combination of Kansas and Minnesota and New York. Flat and cold and a touch pretentious.
Been to 38 states. Missed Texas & New Mexico(will get to both this year or next); Arkansas,Kentucky(I think of Deliverance and road gangs when I contemplate visiting there)Louisiana( not into visiting murder capitals),Massachusetts(too many Red Sox fans );Idaho,Wyoming,Montana(too many white power freaks and survivalists);Maine and Rhode Island however I would like to go to and I missed one of the Carolinas but can't remember which one.
My pick for best and worst: Oregon...the best. Mississippi the worst.
