Letterboxing is an outdoor activity that combines treasure hunting and stamping. From June 17 through August 29 there will be a letterboxing trail within Windham, set up by the Children’s Room. Instructions and personal kits can be picked up to start you on your journey. If you have a rubber stamp that you would like to use to mark where you have been, bring it along; if you need to borrow one, we’ll have some to loan. Families are welcome to take part together.
