Going through old family photos is a trip! I have no idea when or where this photo was taken. Coulda been when my dad was in the Indian Service amongst the Assiniboine Sioux on the Fort Peck Reservation in Montana in 1914 or twenty years later around my uncle Gordon's placer claims near Bumble Bee AZ. I tend toward the latter, but ¿quien sabe?. Thanks ta the interwebs I getsta look lotsa stuff up!
The sign in the upper left says 'Western Union - Telegraph - ?' I can't make out the 3rd line. Could these gents be waiting for a telegram to come in hopes one of them will get to ride the bicycle?
