A sign on routes 8 and 137 welcomes drivers to Smithfield, “Maine’s only leap year town.”

The town’s 2015 Leap Year Parade in celebration of Smithfield’s 175th anniversary last year makes it way through the village in August. The town says it’s the only one incorporated on Feb. 29, and officials hope residents will approve $500 a year to put in an annual leap year celebration fund.

The store in the town’s village is under new management and scheduled to open next month. Residents will be asked at Town Meeting next month if they want to add $500 annually to the budget to fund a leap year celebration.
