In the interior of Alaska we have no=nada=none avalanche warning system. It is up to the individual to educate themselves, there is an avalanche school. I lost three friends in two years, mostly I believe due to the odd weather we had for last year and the year before. Before, no one in our group wore beacons or probes, a few carried shovels for obvious reasons. We had many near catastropke situations during this period, I am sure some here read about the Avi that killed 6 sledders at one time, that was 4 years ago, I think.
The best equipment you can have is common sense, like in that picture I showed with the guy high marking around his friend, the reason there are no other tracks on that mountain, slides were coming down all around us, we decided to stay off the big stuff that day.
Losing my friends so close together is one of the reasons my signature line always says "RIDE SAFE"
