Restrooms will be open adjacent to the sit location and we will have plenty of binoculars to share and a few scopes on site. There is parking in the lot and accessible parking spots. A full description of the event’s accessibility information is included on the registration page. Join us with friends, family, kiddos, a partner, or just yourself! We recommend bringing a chair, blanket, water, layers, or whatever you need to feel comfortable for a morning of stationary birding.
