| http://www.w3.org/ns/prov#value | - I have been doing this so long all I really need is a good compass.In the center part of the USA most of the birds are between 35-46 degrees,I can point at them after looking at the compass.I almost never get paid to do a failed LOS survey,If it fails LOS I get in the truck and go to the next call.There was a time whem there was a $25.00 payment for a customer contact & survey.
