The art of Scavenging (according to a recent episode of Jerry Springor, scavenging is most definitely an art) can be a very painstakingly slow process requiring reams of patience and dedication.  And sometimes you strike Cameron did with his wooden box.

To be really successful, make friends with the scrap heap owner...he may even give you junk, *ahem* I mean potential treasures, for free!

There are 2 scrap yards in Grahamstown for you to try your luck at, Roxcell which is located just past the Golf Club on the outskirts of town and there seems to be another one nearby Roxcell (not sure exactly where) but most scrappers seem to recommend Roxcell. Have fun!
