There are lots of colourful little scenes like this one in San Miguel de Allende. The trick is to find a safe spot to paint them from! The sidewalk here was about 2 feet wide with lots of pedestrian traffic, and cars parked on the narrow street beside it. I didn't want to block the busy sidewalk so I located on the street, at the edge of the sidewalk, after a car miraculously pulled out. So, I painted happily for a couple of hours, feeling a little guilty that I was taking up about a fifth of a potential parking spot, struggled a bit with those exact tints; at first erring a little on the saturation as opposed to glare side, - all in all having a very enjoyable afternoon. No one seemed to find me "in their way". In fact most seemed very appreciative, indeed. Just when I'd gotten well used to the idea, this Mexican lady pulled up in her rather nice car, to a dead stop in front of me, put it in park, and started haranguing me at the top of her lungs. It normally takes a lot to get a Mexican upset. This one must have been having a muy malo dia. She repeated half a dozen times over, that the spot I had my easel on was for coches solamente and I had no business being there. I tried to be nice, but as the traffic backed up behind her we were facing an increasingly serious traffic jamb. I finally dismissed her with a "get moving" in Espanol and she just about went ballistic - I thought she was going to exit the car and come after me swinging. The long lineup was honking by this time, so I guess she finally thought a retreat was in order and with some final cussing hanging in the air, wisely fled the scene. I started cleaning up just about then -the spell having been more or less broken.
As I say, there are lots of great pictures to be made, but it's hard to find a good vantage point from which to paint on the street. Dan Rueffert used to park his half ton truck on the street, and paint from the box on the back...not a bad idea. If I was not moving to the coast soon, I would give that solution the consideration it deserves. Of course, that way you'd be taking up a FULL parking spot - ah...the guilt!
