PARKING – The Justice Center lot will be accessible from Oppenheimer, and is a suggested parking location for exhibitors. Let Traffic personnel know you are presenting at Discovery Day. You may also unload along Central Ave. and then park elsewhere. Please move your vehicles immediately after unloading/loading as we are trying to keep Central Ave. free from vehicles.
SPACE/ASSIGNMENTS – Space assignments were made according to the needs of exhibitors and the festival as a whole. Please bring your own banners to advertise your organization. A map will also be provided via email attachment. The main aerial map will be shared publicly with media and there will be copies of all maps during Discovery Day at the Los Alamos MainStreet/INFO booth.
ELECTRICAL HOOKUP - A limited number of electrical outlets were booked in advance and will be labeled with your organization's name. If your booth is highlighted in yellow on the map, it means we have reserved electricity for you. Exhibitors who booked must provide their own 100’ electrical cord that will be plugged into a distribution box. Also bring a cover for your cord so it does not cause a tripping hazard, if it will be crossing a walkway.
WIFI – If you need access to WiFi, we have been told to use the “ladiscoveries” connection, as that will offer the fastest service.
ASSISTANCE – There will be volunteers around to help you with any questions or needs you might have; they will be wearing orange T-shirts, and ScienceFest Staff will be wearing tie-dye T-shirts. Please visit the Los Alamos MainStreet/INFO booth (#13), or call one of the organizer contact numbers listed below, should you not find immediate assistance.
EMERGENCY – Our info booth will serve as the Lost and Found. Any children who become separated from their parents should be directed to our booth, and we will assist. In case of emergency, please contact the nearest staff member.
