VFR Denver Jeffco (KBJC) to Greeley (KGXY). What altitude is best?
Distance is not far (25 miles or so), so no need to climb very high (to
catch tailwinds). Over moderately populated area of 5000', so need ot
be AT LEAST 6000' high. Denver Class B is at 10,000' and 8000' above,
so want to stay below those, Ft Love (KFNL) approaches, which are in
practice and along the route are usually flown at 7000-7500', so avoid
those. It is determined best altitude is 6500' (might as well obide by
the hemisphere rule at least so far as flying the 500's even though I
am less than 3000' AGL and dont legally need to).

And that is without any clouds to consider.
