Crutches,cars and coupons

El Cobre Cathedral, at the base of the Mountain exploited for its copper, has an altar of miracles where people throw away their crutches and canes. Not a good place to open a prosthetics business.
BUT a fabulous place to be an auto mechanic or restorer. I've never seen such combinations of models, styles, rivets and uses for Bondo.
