The Woolly Mammoth Lodge is a group of great guys. Yes, that means they are a fraternal order, sorry ladies - I'm sure that they would be happy to accept a sister club / organization if one were looking to start up. these guys gather for socials on Tuesdays - except for the first Tuesday of the month where the club business meeting is held. The primary business of the club is to find creative and fun ways to serve the community and raise funds to give to graduating High School students of Pittsburg High School scholarships to help with the cost of education.
The organization does great work and has fun doing it. I've volunteered in the beverage booth at the Pittsburg Seafood Festival for the past 2 years ('09 & '10) and had a blast - I'll continue every opportunity I get. I've also helped out as a volunteer at the Dublin Fun Run for the organization, putting out course markings at 4:30am doesn't sound fun, but with the guys it somehow still is. I've done other odds and ends type volunteer work, providing event security for other non-profit functions and helping with parking at local concerts and events to benifit the Pittsburg Creative Arts Building restoration project.
The lodge also puts on a golf tournament in October - that I just play in, it was also a really well run tournament with a nice dinner afterwords at the Discovery Bay Country Club. Entry is reasonable and the guys that volunteer to run the tournament are great hosts.
The lodge is basically a Gen X version of the Lions & Elks - there are younger and older members, but the bulk of the group membership consists of 30-40 year olds.
If you are looking for a good group of guys to connect with that want to give back to their community, you should look up the Woolly Mammoth Lodge.
