Thanks for the info, Rob and others.
I stopped by Blue Springs a few weeks ago and got 'run' off of there as well - not by a landowner but by a hunter nearby (very nearby) shooting in my direction. I then went to Lil Piney and had a terrific day. I'd like to go back to BS again some day though. I also want to try Mill and Spring as my preferences tend to lie with the smaller, wilder streams than with the larger stocked places (generally speaking, I can have a good time as long as there's water).
