When I was BOS based in 2002-2003, there was revised guidance that came out on the RNAV departure off of 27 that CONSIDERABLY narrowed the corridor. Not sure if it's still the case.

RNO can be a PITA.

The bridge visual into SFO can be fun. You're usually left pretty high, as well as have speed restrictions such as "keep the speed up for the 74 behind you but don't overtake the Brazillia landing on the parallel."

Only as hard as you make it, or if you're an FO, how hard the CA wants to make it. It's not anything more than a downwind entry with landmarks and reference points for the base/final. Super easy if it's in the FMS data base on an VNAV equipped airplane. At least till the controller tells to you square the base to final for seperation.

A fun approach, especially when right at mins an using the lights. Even cooler to be on the ground and watch a heavy doing the sidestep to the right.
