I was out riding with David a week or two ago and spoke with him about half wheeling. The annoying habit of riding half a wheel ahead of the person next to you when riding doubled up. It forces the person behind to keep speeding up. David had never heard the term before and suggested I put some educational pack riding stuff up on the website.
I am just a puddin'. I am no expert rider but I try to learn as much as I can. So here is a great link on group riding skills. On any one of our rides, I see us breaking all the rules. Still fun though.
