Let me say that I have received a few shots that are above and beyond calendar quality, I'm talking hang on the wall art!
Which does bring me to another idea, if the photos are high enough resolution I can see about getting some posters printed along with the calendars. 14x17 or something like that. Just some food for thought.
Keep those pics coming in, this is shaping up to be the BEST EVER c-c.com calendar!
