Here an updated list of local comic/science-fiction/anime/etc. conventions in the Colorado area in 2018! In this update, I added one more conventions that's not in Colorado, but it is only 15 miles over the border in Cheyenne!
NOTE: This does not include gaming conventions. I thought about adding them, but decided against it, just because I'm unlikely to ever go.
