I was at coleman in 1959-1960. I spent many nights guarding a sealed entrance to underground hanger. We had to guard it at night to prevent entre by souvenir hunters. "we were told it was boobie trapped" the
location was on northeast side of concern. just east of our mess hall
and officers club. It was located in dry river bank, which does not
show on map now. my # 541 837 8507
