Lots of good places, particularly if you're not stuck downtown where the traffic is worse. There are a number of good rides posted on the Swami's ride calendar, which then hyperlinks to RidewithGPS. Here's the link, and feel free to PM me with any questions, as I've ridden pretty much all of them.

Also, note that the weekday rides tend to be shorter loops, whereas the weekend rides are longer (50-60 miles, or more). If you check out a two month period of Saturdays and Sundays, you should have a pretty wide variety to choose from.
