I've belonged to TU for years. My only gauge is what I see in their quarterly
Trout magazine and their direct mailers. They're definitely doing lots of conservation work and appear to target certain local issues.
I was very impressed with their winter 2007 consumer's guide to why eating wild Pacific salmon was better than farmed Atlantic salmon, not only for your health but also for the environment. I wish they would make PDFs of this article available to anyone to download, instead of requiring that you had to be a TU member to read it. (Marketing 101...many people would end up joining any way after reading the reprint.) That's something that a national org probably has more resources to accomplish than a local org, but I wish they had taken this a bit further.

So Rick, I can see why you're questioning the value of your membership in terms of local impact. I guess I've always felt there's value to a national org and as long as the membership fee is in the reasonable range, I'll continue to pay it.
