NO FIELD TRIP REPORT
CCMGS takes safety very seriously. All members must sign a field trip waiver prior to participating in any club-sponsored field trips or outings.
We ask all members to review and retain a copy of our safety recommendations and basic field trip information for their records. Members can print, sign, and bring their waiver to the field trip or submit it to the Field Trip Coordinator prior to the trip date.
