from surveying in the heat of the dakotas, to the islands of arkansas, to the winters in michigan, they have performed well. that’s how i came up with these tasty little treats. i can't stop them from making me dance. i am not sure why it took me so long to make this purchase. the key is to have your players not popping up with each whistle but staying in that nice low hockey position hips down and toe/knee up against the boards, each and every time your whistle blows. the event is free and open to the public.
