Linked cities above go to city pages on a wiki. Well over

1037 cities have participated from 88 nations or subnational areas since 1999. The overall city list linked just above is no longer up to date. So many cities have done 420 and GMM events the last few years that it is too time consuming to create so many new city pages.
Anyone can edit existing city and country pages without logging in. For example; to add links for Facebook groups and pages, and other links. See city format for ideas.
Red-border cities above (on the 2023 city list and before) do not have city pages on either wiki.

Yearly event links and graphics are often not added to city pages due to the amount of work involved. The links are found in the yearly city lists and maps. Graphics and photos can be found in this alphabetical flat list by city name. It contains only a small representation of the many GCM/420 graphics and photos over the years.
