The Calendar Decision

I have decided to make a 2013 calendar of the photos I took while touring the national parks in the Canadian Rockies this past summer.  I took over 6000 photos on the 23 day road trip, and have narrowed it down to the 15 I think are the best.  

But, I can only have 13 photos in the calendar, one on the cover and one for each month.  So, I am looking for some advice on which two I should remove.  The photos I am considering are in the slide show below.  

Take a look and leave a comment to let me know which two I should remove.  

Also, once I finish the calendar it will be possible to order one.  If you want to be notified when it is possible to order enter you email address below and will send you an email once it is ready.
