The event is called 'Puttin' On The Dog' and is an annual charity fair.
Most proceeds from the event go to the charity Adopt-A-Dog.
There is plenty of free parking available across the street from the park.
A few nearby places worth checking next.
I have been using it now for 3 months and it saves me so much research. Reduces the need to call and double check every time.
How did I not know these places existed?! Atly's scoring is a lifesaver, now I can finally find THE spot without wasting time Googling my life away.
