Ok, so I am a little late on this but in time I will be on top of things! This past weekend was the Pomona Artwalk in downtown Pomona where the art culture is rich in the Inland Empire.
If you are in the IE and want something to do, every second Saturday of the month Pomona has an art walk that is full of galleries having shows, providing snacks and sometimes wine, local bars, and lots of restaurants to grab something to eat during your journey. It is several blocks of all of the above and a guaranteed good night for all. There is also local events all month long in the downtown art district like the weekend Farmers Market and every last Saturday of the month is the Pomona Night Out Classic Car show. Several times a year there is the Antique Rows collectors Street Faire (Next one is on May 25, 2013 8am-3pm). (This is so dangerous for me not to spend every last time on the treasures found here!
