No CHer, you came in while I was tallying the others. I just saw yours, and you are now in the lead, but only beating cpdad by a point.

Ok - here are my guesses - no laughing though - I'm blaming my ignorance on being new!
(though given the amount of reading I've been doing since I got a little rock in my blood I feel like I should know more of these...)
1. a
2. b
3. d
4. a
5. a
6. b
7. b
8. c
9. b
10. b
Are we disqualified if we admit to using the eenie-meenie-my-nee-moe method on one or two of these? I'd like to know that before I say anything else...
Thanks for the contest!

Players so far today ahve scored between 3 and 5.
Socres have been a bit low, and I am more uneasy than I thought I would be telling folks they scored low. Two folks are tied for high score with 7/10. Cher was the 1st to get 7.
I guess I figures there would be some googeling or maybe searching of RTH threads. I also figured that nobody after Cher would change more than 3 of her answers since I had posted that she got 7 out of 10. Seems most people approach this differently than I would.
If nobody scores more than 7/10 by 11:30 tonight (EDT) I am going to call it for Cher.
Once the answers are posted, maybe we can have some follow-up discussion.
