A Walk Around Grove

It's so happened that I'm nursing some yellow jacket bees on my deck because of the flowers I have there. So bees decided to make a home of their own on one of the wooden beams. I decided to let them be as long as they din't bother me. I was walking through streets of Grove part of Jersey City and I found some trees and land horse chestnut leaves to draw. The leaves were facinating because I have never seen a compound leave with 7 leaflets with unusual looking round pricky fruit. I had to look this one up in my tree finder guide.
