During the school year, leaders provide weekly meetings to help the boys work towards their next rank and acquire the skills to prepare them for Boy Scouts. Meeting only when school is in session, the Pack meets at the Lutheran Church on Mondays at 7:00 pm.
Sharing a portion of Highway 22 in just outside of Centralia, Pack 90 maintains a mle of the highway going back into Centralia. The boys of Pack 90 meet at least twice a year to pick up trash and ensure that portion of Centralia stays picked up.
An annual event of Cub Scouting is the Pinewood Derby. Each year, the boys of Pack 90 gather to pit their Pinewood Derby cars against each other. The boys and their parents are encouraged to work together to create and decorate the boys cars. There is also an Open Class for former Cub Scouts and parents to compete.
