Four bags of cubes at the gas station in Girdwood was $10... About 20 lbs worth.. Besides glacier ice makes my Margaritas taste better.
You don't have to use Blackstone, there is ice coming off all the glaciers, just have to look for it. I will admit that running up Blackstone is a pain sometimes but you can fill a cooler fast and it lasts a long time. I just use a screw driver and fish bunker and break it up.
I get the glacier ice also. I keep a small landing net on board and let my kids dip net for ice bergs. If it wont fit in their net its to big for the cooler, that way I don't even have to break it up. Yeah pulling into the bay and stopping for ice could be seen as an inconvenience but when i'm out on the water with my kids I'm already at my destination and my time is free!
