Also, check around with the museums.
I believe at least some have free admissions
one day per month. Sorry I don't have
solid info but I believe the Chinese
Heritage museum (or some Chinese meseum)
is free on one Wednesday per month.
Also check out your neighborhood
community center. I have noticed that
they always have some events going on
which is free. I can't comment on how good
they are but it's worth a try.
Good luck
