Thanks, Alex! I got the PDF you sent me. Actually, that
is the audience I have in mind for my flyer: non-orienteers passing through the Frisco Nordic Center.
I found BAOC's 2012 Ski-O Tour bulletin:
link. It's a multi-page bulletin, not a flyer, but it has a great look.
Hammer, I bet this is the Kootenay poster you mentioned, but all I could find was this tiny thumbnail. You're right, though -- it's very sharp.
