I think most of us that have paddled for any length of time have paddled alone, but the smart ones are picky about which streams that tackle alone

. I wouldn't have any problem jumping on Elkhorn, the Pigeon, Ocoee or even the Tellico or Little alone. All of these are reasonably accessible, generally have someone else around and are well within my skill range. However, I would hesitate to run OBJ to Nemo by myself even though I'm extremely familiar with the run just because the chance of someone else coming along the river is small and access for search and rescue groups is pretty bad if something did screw up.
Just my opinion.
