Howdy all you working buskers!

Has anyone ever worked the Gem and Mineral show in Tucson?
Many years ago I had a Mobil coffee trailer and we did very well there.
Tons of people and many are from Europe.

Been years since I’ve been and have never worked the streets busking during that time of year.
BTW
Tucson has a great event called 4th street arts fest twice a year.
Need to register with the city.
Thanks,
Nickoli
