Trivializing the discussion & promoting paranoia regarding bears does not serve mountain bikers or bears. People can successfully co-exist with bears when we take them into consideration & make the effort to avoid conflicts, especially obvious conflicts which this proposed trail system is. 

If you are that paranoid about grizzly/brown bears, well there are over 40 states in the Lower 48 that do not have them. I suggest that you move there were taking out the trash is not such a risky practice for yourself. 

Furthermore, Anchorage's and Alaska's grizzly/brown bear population is what helps make Alaska unique among all states. Analyzing the issue & using common sense to avoid obvious conflicts is in the interest of all Alaskans. 

While I certainly do believe in asking questions of Rick Sinnott to better understand his data/position, his committment to the safety of both people & bears has been well established. I would ask that STA re-evalutate their position & look for alternatives.
