I just posted this on another thread about drafting, but wanted to share here too.
I can't say I've drafted for any length of time before, but I just happened on an opportunity today. A lawn maintenance type truck was in front of me to turn right and I followed him. I knew the road to be mostly flat and even somewhat downhill, so I got a few feet behind and stayed with him for almost a full mile. Once we were up to speed, I only had to pedal every few seconds. It's a 30mph road and I clocked 29.2 for that mile. What a rush!
