I understand completely. The people I ride with on a regular basis all have some sort of radio-thing (helmet to helmet intercom, etc.) and I'm one of the lone hold outs. I ride for the joy of the road... the interaction with the machine and the road... and sneaking-in views of the world I'm riding through. The last thing I want during this R&R is "chatter." Hand signals worked well years before the advent of small helmet-based communication devices... sometimes "technology" takes away from an experience (IMHO).
