One of the great things about living in the East Bay is that there are literally a dozen parks designated as open space throughout. None of this land can be developed and for anybody who has been to the bay area lately, undeveloped locations are hard to come by. I am fortunate enough to live ten minutes (3 miles) from one of these parks. It is Black Diamond Regional Mine Preserves. Besides the close proximity, it is really a beautiful park with a diverse landscape. On top of that, the dogs are allowed to run free. It's almost like 1000s of acres for my backyard. This particular park has over 65 miles of trails that cover all types of territory. Over the past seven years, I have hike almost every mile with the dogs many, many times. The park looks different at different times of the year. There is a softness to the lighting in the fall that really appeals to me. I added a photoshow of today's hike. These are some of the things we saw during our 3 1/2 mile walk.
