I get about 2000 spam emails a week, most of which get filtered out automatically. About 1 in 4000 of these end up being a message from a customer that should not have been filtered .

To bypass my spam filters, please include one of the following words somewhere in the body of your email:

UTM, MGRS, longitude, compass, coordinate
