The first printing of PARKS (Fall 2019) contained 15 Forest and 15 Mountains, but the rule book indicated 16 Forest and 16 Mountain tokens were to be included. The game was designed and tested at 15. The update to 16 was a desired cosmetic change to even out the number of tokens between the two resource trays that made it into the final rulebook, but not into the assembly process.
These tokens are not required to experience the game as intended, but they are available for the cost of shipping. Additionally, they will also be made available at any Keymaster booths at a convention at no cost (while supplies last).
*Limit 2 per order, but if you one need one, please only order 1
