The Pioneer Press Treasure Hunt is part of the St. Paul Winter Carnival every year. While the prize can only go to one winner, The Allison Wonderland is dedicated to the community spirit of treasure hunting. Here, not only will you find out about the Pre-Dig Gig, the Rehash Bash, and various other social events, but we also discuss the clues here in a team effort to decipher them (albeit not always successfully).

This is a public group so expect that anything posted will be seen by everyone.
