If you have avoided other Mt. Si trips due to fear of slowing down the group, this is probably the group for you. If you like to go fast, you will probably get bored with us. I anticipate getting to the top in around 2:30 hours

Dress for a chilly break atop Mt. Si.

Traction device will be required. Yaktrax or micro-spikes recommended.
