Got a reply from Daniel Richardson, and it appears to be an honor system type run. There are two starting points, Plymouth and Greenfield(closer to me) and both end up meeting at City Hall Plaza. There will be placards/write ups like this;

THIS CAR'S EFFICIENCY REPORT

DRIVING FROM GREENFIELD IN MIXED DRIVING CONDITIONS, I DROVE ________MILES

AMOUNT AND TYPE OF FUEL USED FOR THE TRIP

___________________________________

THIS REPRESENTS AN EQUIVALENT OVERALL EFFICIENCY OF ________MPG

USING THE PRESENT COST OF THIS FUEL, THE TRIP COST ____CENTS/MILE

CALCULATING EFFICIENCY (car owners only)

If you used gasoline, simply divide miles by gallons

If you used diesel, divide miles by gallons and multiply by 0.95

If you used electricity, insert the KWH you used into this formula:
KWH used divided by 33.7 = equivalent gas used. Then, divide miles driven by this equivalent gas used. This will give you a plug-to-wheels figure. This plug-to-wheels figure does not account for the
resource consumption (and carbon generation) of electricity.



Multiplying the plug-to-wheels figure by .46 will adjust for the relative efficiencies of supplying electricity-to-plug vs gasoline-to-pump

If you used wood and gasoline take pounds of wood you used and divide it by 13. This converts wood energy to gasoline gallons. Then add the gasoline you used. Divide the miles driven by this total gasoline
equivalent to get MPGe.
I'll ask about specific locations to meet and routes. Any other questions?
