I'll try this year, starting at Pike's Peak:

Pike's Peak: Read 12 books from your TBR pile/s
Mount Blanc: Read 24 books from your TBR pile/s
Mt. Vancouver: Read 36 books from your TBR pile/s
Mt. Ararat: Read 48 books from your TBR piles/s
Mt. Kilimanjaro: Read 60 books from your TBR pile/s
El Toro: Read 75 books from your TBR pile/s
Mt. Everest: Read 100 books from your TBR pile/s
Mount Olympus (Mars): Read 150+ books from your TBR pile/s

As you said, I can always switch up. Between my Kindle and my bookcases, I'm sure I have enough books to go for the 36-book level, but I like to leave room for new authors I find or best sellers (especially political best sellers) that I want to read hot off the presses.

We'll see how it goes. FanSee
