I talked to Paul Arnold at of Summer Jam West 2019.

Tell me about yourself and what you are doing today.
I have been doing chalk since 2014. I do it about five or six times a year. Today, I am doing John Lennon. I am named after Paul McCartney. I figure I would do John Lennon since it is the peace train. I have been an artist since I was sixteen. I went to Ringling Arts School in Sarasota and graduated in 1989. I just moved back to Ohio about five years ago. There is a big chalk scene in Florida. The weather is perfect there all year around. I’m glad they have a chalk scene here.
Anything else?
Give peace a chance. Imagine peace because that is what the world needs.
