Charcloth, you aint just whistling dixie about Mapquest, hon...MAPQUEST SUCKS!
After a hellish drive to a gig out in east BF podunk Maryland that involved a flat tire, a speeding ticket with a half hour lecture from Officer Friendly, we found that the directions we printed out via Mapquest put us roughly within 5 miles of where we needed to be. Funny...we tooled around for quite some time, but it just wasn't good enough to be somewhere within a 5 mile radius of a secluded wilderness camp.
Next time, I take a divining rod instead. ;)
