A few years ago, I was in Georgia, and decided to drive into Tennessee to see Ruby Falls. I only had the house for maybe 6 months and only visited on weekends, once a month, so I was clueless when it came to getting around. I got directions off of Yahoo and went on my way...the directions were so F'ed up that we were lost within 30 minutes. I eventually got directions from a local at a gas station and his directions were SO MUCH EASIER.
After that, I decided not to rely on computer directions.
