We go there fairly often, our grandson loves going there...often. Our adult children went there sometimes when they were young. We went today (3/30/2018) feeding the fish, you can get fish food for free from the visitor center. When we went to the visitor center the docents were particularly friendly and helpful. I really appreciated the fun, educational atmosphere. When we went out to the long concrete troughs full of water and fish in various stages of life. A worker was driving next them with a pickup truck that was towing an appratus that was shooting fish feed into them. He eventually asked if we would like to come inside an adjoining building that was hatching fishes en mass and rearing them in smaller stainless steel troughs. He gave us an impromptu tour there and even gave our grandson a small toy he had found in one if the fish rearing areas. I can't tell you how great and special that was! We finally went to a playground that helped perfectly end the visit. All in all I highly recommend and we will be back!!
