why not make it once a week. we can all benefit from extra excercise, or maybe even better, make it ride to work week, just imagine the lost revenue if 2.5 million motorist did not pay for petrol for a whole week.
as a costing thing once is fine... remember its a good thing to encourage other to ride... but who is paying for it???. Most of the food and other items are donated but some do cost. and its hard to get the help from outside groups as well as Vollies to give up their time.
