i also ran over a soft spot about 20 yards in diameter of slush. i dropped down about 6 inches on my atv, did not like that at all. i saw about 10 pickups out there, and they sure made the ice pop when they drove by. if your gonna drive out in a pickup this early stay 300 yards away from me please.
that bad spot has made me a little leary of taking my six year old out just yet. it was covered with snow and i could not see it. it was about 150 yards out between swim beach and northshore bar and grill.
