I was a newbie once. Everyone was. I don't mind reading repetitive posts so much. I have the choice of reading them or not. You always have to use your filters on the internet, right?
Anyway, I consider it a tour if it involves an overnight. My shortest tour was when I took a bunch of 6th graders to our local state park. They wanted to try "touring". We rode 2 miles, camped, and rode two miles home. Total mileage: 4 miles. Total fun: lots!
