HELP needed to find street food vendors
i'm doing a photo project on street food vendors in dc area that are willing to be photographed. i need a diverse selection. i've got the burrito guys on K st. i had a pupusa lady (maria - truck name is aqui y alli) in arlington but she relocated and i can't find her. i know what i'm looking for is:
1. a diverse (as in what they serve)list of vendors with addresses
2. if you know where maria and her truck "aqui y alli" relocated
3. if you know of some arlington cty or dc official with is a liason with vendors that could do the intro. because soooo many vendors are leary of being photographed.
