"Mt. Si would be a fun day-hike near here."
With that potential number of people, it might be well to spread the day hikes out a bit. There is an alternate trail on Si starting at the Little Si parking lot that is much less traveled and steeper, a very nice hike. There are also excellent day hikes on Mailbox and Teneriffe via the SW ridge for those who like their exercise in stronger doses. Allow an extra post hike beer for those who choose either of the latter. ;0))
Edited for grammar.
