I just started actively looking for militaria at our facility this summer. It boggles my mind... I am sure a lot of other militaria treasures have passed through our facility unseen in the past 6yrs that we've been open.
You'd be amazed what people throw out. We've found locked safes filled with coin collections, cases of liquor from the 1950s, brand new power tools... and the most intimate personal documents you can imagine (both financial and sexual...). Objects certainly DO NOT disappear when you throw them out in the garbage... KEEP THAT IN MIND AND INVEST IN A DOCUMENT SHREDDER!
