The Old Mill in San Marino is such a wonderful setting. The historic adobe building from 1816 is surrounded by lovely gardens and fruit trees. The last time I painted there was in January, Old Mill in January. Since it's summer, there was a possibility of very hot weather but the day was perfect. In 2012 when I had just started plein air painting it was over 100 degrees for our Saturday paint-out at the Old Mill. Special events are another possibility there, especially on a Saturday. Sure enough, at one point a woman told us that people would be setting up for a wedding in about half an hour. We were painting where the wedding activity would be. I painted a little more quickly and finished up as arriving planners and flowers started blocking my view. Plein air painting can be exciting!
