Morrison wouldn't be too bad of a commute, since Morrison is right at the edge of the city-- I'd say it's a 20-minute commute during non-rush hour times, add 15-20 minutes during rush hour. Conifer would be a longer commute, probably 35 minutes during non-peak times. Either would be a pretty easy commute, though, straight down 285 (which generally doesn't get too congested during rush hour-- the worst areas are around downtown Englewood, which is mostly due to stop lights not being coordinated in that stretch). I'm not too familiar with the Conifer area-- there is a lot of development going on around there, including a new shopping area, but apart from that I don't know too much about that. So hopefully somebody else can help you out there
