Tony was nice enough to send a quick e-mail to fill me in on some more details about the blind at Lost Maples SNA. In short, the blind itself is not very photographer friendly, but the birds are accustomed enough to humans that shooting from the picnic tables directly outside the blind is workable. He provided a list of birds that he caught last spring and there were enough birds that I do not have images of (in particular the Indigo and Lazuli Buntings) that this will be high on my list of places to go next spring.
Thank you again, Tony for the information. Expect an initial blind report sometime in the spring.
