Vanners,  [NorCal type especially]

There will be a non superbowl party this Saturday night/Sunday.  Scheduled
for Rio Vista at a public park at the end of Beach St.  Go downstream on 2nd
street until it forks, go left it turns into Beach St.  At the end is a
park.  This was posted on the syncro list which probably has better
directions.
