It is too soon to know if we will have an in-person meeting in February or go back to zoom virtual meetings. Please read your email from our reflector.


The next meeting will be Tuesday Feb. 1, 2022. If it is in person, then it will be at at 5:00pm. We have reserved the Summit Room within the Sports Basement store in Sunnyvale for 5pm on the first Tuesday of each month. They close at 7pm so that is why the meeting time is so early. The meeting will be in the separate community meeting room in the back right corner of the store.
The address of the Sports Basement is:
1177 Kern Ave
Sunnyvale, CA
