When I file RHV-STS (IFR) I put "Unable STINS" in the Remark section. ATC
usually comes back with (a much better) RHV-OAK-SGD-intersection-Direct
(or something like that, it's been a while...), or it might be "RHV, radar
vector SAU, direct" - both are much better, safer, and more direct.

Agreed. My original plan was SQL RV OAK, Point-Reyes-VOR and a
few victor airways up to Ukiah but got that instead. Next time,
yes, I'll say unable for undesirable routes. I definitely
learned my lesson(s).
