Pumpkin carving is part of the Halloween tradition but doing it underwater
For 27 years, the Minnesota School of Diving - Brainerd has hosted an
underwater pumpkin-carving contest on the last fun dive of the season, which
is the weekend before Halloween.
Through the years, up to 30 scuba divers have participated and usually about
16 carve a pumpkin. According to the Minnesota School of Diving owner and
founder, Bill Matthies, the contest is always in the Cuyuna Country
Recreation Area and has two main categories.
For the first category, a diver may only use his diver's knife, and the
second category is for pumpkins carved with special carving tools.
Prizes are given each year, which vary from the pumpkin that looks the most
like the dive master in charge of the contest to the scariest appearing.
This year, dive buddies Paula Persons and Leslie Kopietz carved pumpkins
with several divers, just enjoying the last fun dive of the season Saturday
surrounded by snow-covered hills.
