Hey Matt, I was out last weekend and went out at Cook's, The group of guys I was with went out from Gilford road where all the up operators are set up. There were between 20-30 there were truck, suvs and even cars parked on the ice near shore, but go at your own risk.
Another point you can access Cook's from Gilford is at the end of HWY 89, you can unload you gear right near the water, other wise it could be a long walk from where you would park along the side of the road on 89
hope that helped
