Fortunately I didn't get spotted, didn't get in trouble, didn't lose a leg, and hopped off a mile or so down the line when the train slowed and I realized I might be in deep kim chi if I didn't hop off pronto and sneak home before anybody saw me . . .
I got on a freight train in Castroville, Ca (Monterey area) and ended up the next morning in the Glendale shipping yards with 50 cents in my pocket.
