I do not know how many bikes converge on Sturgis in mid august
but i think it might be 1/2 million or more...last year was the
70th anniversary of that rally...not known if there are toys
involved other than big kids toys...biker's toys...etc. I tried
to travel and camp in the black hills during the 50th anniversary
and there were no vacancies for 500 miles in either direction.
