Turn in your results by 1:30 pm the afternoon of the telescope tour.

Rules of the scavenger hunts:
        1.   Some questions are labeled (F: first timer) and (R: returnee). First time attendees should focus on the "F" questions; returnees on the "R" ones. Everyone should answer the questions without designations. In all cases, return attendees shall not reveal the answers to first timers until sufficient effort is expended. (And, any bribes must be shared 50:50 will the Scavenger Hunt creators.)
        2.   You may consult any source anywhere but please be sure to indicate where you got your information. And watch out for bad websites! Actually, if you find any mis-information, make a note of it for the blog.
