Started with, and startled by, the overland route to Delhi in 78, from Athens. I'm Canadian, partly retired. My plans are always flexible.
I do like to be inspired to enjoy museums, ruins, mountainous regions, small sojourns on a beach and good food. I now prefer to break trips up into 6 hour legs, if possible. There's usually something good to stop for after that amount of time.
Small amounts of luggage, a willingness to overlook less than comfy situations, and enjoyment of the people and details of the surroundings make me smile.
