Two cool sites I love!

American Visionary Art Museum in Baltimore, MD features American outsider, visionary and folk art. I've visited the AVAM several times. I try to go every time I go to Baltimore. If you take the fun Baltimore Harbor water taxi to AVAM, the taxi service will give you discount tickets to AVAM.
AVAM also gives student & senior citizen discounts.
Thrift Store Art is an online gallery (and sometimes offline) of quirky thrift store art finds.
