I remember I was 19 when I hired out to the D&RGW..I heard the Road Foreman at Alamosa was squeezed a bit for firemen, and I borrowed my grandad's big Pontiac to drive about 180 miles over there that same day from where I was (Fowler CO.) and see him...it worked out. But if I had diddled around, I wouldn't have been hired at all.
