The "L Train" (15" x 18" Pastel)

Recently, I've been traveling by subway to Williamsburg, Brooklyn. That's the home of my daughter's accessory business, BOND Hardware.

Traveling by train, you can't beat the people-watching! You always see some interesting folks.

I always wonder if it's kosher to take pictures of people without their permission, to use as a subject. I do that all the time ... thoughts?
