There are 900 of them going on around the world tomorrow, July 18th.
Many of the walks are at capacity, but I would visit the Worldwide Photo Walk website to see if you can still sign up for one in your neighborhood.
I am leading the Saint Paul walk, and there are still 3 spots.
From the website:
Q. What is a Photo Walk?
A. It’s a social photography event where photographers get together, usually in a downtown area or trendy section of town, to walk around, shoot photos, and generally have fun with other photographers.
It sounds like a lot of fun, and I am excited to participate tomorrow.
(I am going to leave this post ironically photo-less)
