hmm, found my real problem, the trail IS complete, but part of it is in VERY close proximity to old railroad tracks, google resolution in the area wasn't good enough to see it unless you're looking for it
as for the rocky parts of the trail, i believe only a 2 mile stretch is "off limits" to bikes, and i can walk this section if i must, may take the pressure off the tires anyway : )
the rest appears paved from all the pictures i've found and descriptions on their website
wish your boss good luck

that's only a matter of time, unless he has gatorskins or armadillos or something similar like that, bumpy ride though
