The Nature Center is set up so that there is no way to get up close to the ponds where the ducks and geese hang out the most. It is for the protection of the waterfowls. They are kind of like the things that hunters and reserch people or photogephers set up to get close to birds or animals without being seen that are usually called 'blinds'. They have put up block walls with square holes in them to look out onto the ponds and where you can take photos. All of these and the ones of the previous post with the geese were taken from one of the 'blinds'.
