Ron,
There are some of us in Eastern Nebraska, and there is a young guy near Columbus.
We have a core group that does get together on the Nemaha a few times a year, I've not done any panning on the platte or little blue river, but my parents live in hastings, maybe i could meet up with you sometime when out there.
My wife and i do get to Colorado a couple time a year, We are planning on an end of Sept Trip to CO , and then perhaps a group Nemaha trip in October after the farmer does his Corn/Bean harvest.
If you have Facebook, ask for an invite to our group:

We still have a messageboard for our Nebraska Group as well but it is not frequented much.
