Hey all, I'm headed to COS, and waffling on whether to fly myself or commercial. I've flown to Boulder & Greeley before, following a route that was vaguely following I80 but a little more direct (thanks to advice from folks here). For COS, it doesn't look like flying further south makes it any better. So for those that do it regularly, any specific routing advice? Plane is an M20J (no turbo, no anti-ice). I can fly IFR or VFR, and 13,5 or 14 is fine. I haven't really gone higher, so I don't know how well she'll fly above that. I have supplemental O2. Will be close to max gross, and I can leave very early to avoid weather. I've done a fair bit of flying in & over mountains, so not particularly worried about that. Mostly looking for a good route. I appreciate any advice.
