Thanks Klaus. How far is the Little Buffalo site from Little Rock? I would like to see C rubrofluviatilis. Do you have a specific site for them? I may be willing to make a detour :) Oh, yes, I'm driving. Anybody have a week to spare and ride along? Hmmm, a week to spare huh ? Let me do some looking here Mark and I might be able to swing a few days.... Charles A.
