Bob, I noticed a similar thing last August. The visual impact of bags on the trail is not the only impact going on, it's just the most obvious indicator. My daughter and I saw, stepped over, or stepped around 10 or 12 bags on the way up and about half as many on the way down. It may be logical to stash them temporarily, but it's still an eyesore for everyone else unless it's hidden and not forgotten on the way down.
