I have plans to visit Washington, D.C., around 3 years from now, and in all likelihood, I'll be going to the National Zoo. For those of you who have been there, what would be your tips and recommendations for visiting this zoo?
The zoo will be quite different in 3 years, as the bird area will finally be open again. Of all the zoos I've been to, it is the hardest for me in terms of walk-ability. You have to do some back tracking and looping, as well.
