The site navigation utilizes arrow, enter, escape, and space bar key commands. Left and right arrows move across top level links and expand / close menus in sub levels. Up and Down arrows will open main level menus and toggle through sub tier links. Enter and space open menus and escape closes them as well. Tab will move on to the next part of the site rather than go through menu items.

Event Details

What is glowing in the dark? Visit Isle a la Cache Museum to discover the basics behind eyeshine – the phenomenon of eyes reflecting light in the night – and whose eyes glow. Just in time for Halloween, spiders are at the top of the list! Then grab a flashlight to hunt for eyeshine. You never know who will be looking back at us in the night.

Please bring your own flashlight; headlamps work best.
