The importance of the policy requiring riders to sign the waiver (sign in sheet) was demonstrated recently. It is also important that the information written is legible! 

After a recent ride there was a non-emergency need to contact one of the participants for a reason that will remain known only to those present.  The ride leader got out the ride sign in sheet, which has places for both an emergency contact number and the riders cell number.  Both these were completed.  Unfortunately the last digit of the rider's cell number was open for debate, was it a 4? , a 9?  maybe a 5? or some other digit?   So the leader tried the numbers that seemed most likely, eventually connecting to a voice mail which did not identify the recipient, just repeated the number dialed.  Was this the rider we needed to contact?  The leader then called the emergency contact number and got a recording again not identifying the person.  A message was left, but everyone was concerned because the rider would certainly need to know the reason for the call.  Fortunately the situtation resolved itself soon after as the rider returned to the start.

Riders, when you sign the waiver, please take the few extra seconds to make certain what you write is clear.
