Yeah I lost like 5 pucks in 2 weeks of playing myself. I can't imagine how many puck there must be under the snow at the park. I should have went there and checked today since it was rainy and the snow kind of melted.
I always just stock up in the summer, buy a dozen used pucks at PIAS. I shoot at the outdoor range around here a couple times a week anyways so I like to have a lot of pucks for that. Then I lose a dozen pucks in the winter and repeat.
