It is suggested that each passenger share expenses with the driver.
Mileage is based on the car odometer, not on the outing schedule.
The leader arranges transportation with the express understanding that those accepting transportation release the leader, the driver, the NMMC, and its officers, committees, and members from any liability for themselves or their heirs, from any injury to themselves or any loss or damage to their property arising from such transportation.
All members are to abide by local, state, and federal laws in the conduct of NMMC outings and activities, including, but not limited to, motor vehicle laws.
Anyone driving on a NMMC outing must (if asked) show proof of license, registration, and insurance.
