Well, I've been meaning to do this for almost a year now. And finally I've finished two more scavenger hunt photo lists: one beach and one forest. I'm happy to shoot over the pdf to anyone who is interested but it may be that the images are too regional for some [i.e. no palm trees on my beach!]. Anyway, if you are interested in these or in my original park one, send me your email address and I'll set you up.
UPDATE: I have these pdfs available at wee printables. Help yourself!
Happy hunting!
