Can anybody recall the last time a sled went through the ice in the Mercer/Hurley area in the middle of February. The reason I ask is because we are staying in a cabin on Island Lake next weekend, my wife refuses to let our seven year old son ride his quad on the lake due to the warm up that is supposed to be coming. Can anybody tell me how thick the ice would be on Island Lake this time of year. My son would really appreciate any help. Thanks
