Ruth and Dan,

The food cart industry is not easy. But many do it with success.
We have been Arts and Crafts venders for over 25 years and have talked to many food venders.
All have stated the frustration of dealing with some state but mostly city and county health and license requirements.
The best source that I can think of for good solid information are food cart venders at large state and county fairs.
I wish you the best of luck in your future plans.

Ruth and Dan,

 

We work for large outdoor music festivals around the country, although not as food vendors.  Most of them have a vendor tab on their website and when you request info, the packet usually includes what you need to do for their location. 

Also, in case you did not already know, their are several websites dedicated to outdoor festivals, one is www.festheads.com.  You can search by locations or venues.  Once you locate a festival or festivals you are interested in, you can then look around the festival's site to see if the info is their or you need to request a vendor's packet.

Hope this helps.
