I did quite a bit of hitchiking back in the seventies. Once, I took two weeks off of work, and hitchiked from Atlanta to Boulder Colorado.
From there, back east to Minnesota, went north and crossed into Canada, crossed Canada north of the Great Lakes and down to Vermont to visit my brother for a few days, and then hitchiked back to Atlanta. Pretty good for 16 days.

Also hitchiked all across Europe in 1973, from the southern tip of Italy to Denmark, and then to England.

I figure I have hitchiked farther than the circumference of the earth, 25,000 miles. Did get lucky one time, a gal picked me up in Nebraska and we wound up spending the night at her apartment.
Now, I would have gotten real lucky had I been a gay boy.

Also crossed the continent hopping freight trains but that is another story.
