RideBoard.com is for those adventurers with limited budgets, no cars or are just plain lonely who want to hitch up with a stranger who plans to take the same city to city trip as they are ... great for college students, sporting event or concert excursions or oneway trips ... also has lots of information for road travelers (e.g. rest stops, ATMs, RV Parks, car audio and weather)

Transtar Transit Routing System - overlooking its drab design, this site allows you to enter your starting point and destination (using cross streets) and then supplies all of the buses/subways to take, along with times and fares. Covers most of Southern California ... kudos to the Ventura County Transit Authority.
