I just returned from my trip to Pismo Beach to see the migrating monarch butterflies. Would you believe that I went off and forgot to pack my long telephoto lens? I was so disappointed. The butterflies are high in the trees and a long lens with a flash is a must. A very kind man let me use his lens on my camera for one or two shots. I was wanting to capture the clusters such as this but it was not possible with my short lens. Next time I will be prepared!! This was my first time to experience this amazing yearly migration. There were thousands of butterflies. I have a few more images but none that show the clustering.
