just when i thought google couldn't get any cooler...we now have google transit. it's a transit trip planner--you can type in where you start, where you need to go, and what time you desire to depart your starting point or arrive at your destination.
but, it has multiple cities! it only has nine systems now, but hopefully it will add more systems as time goes by. it's now in testing. but, it will be so shiny when it has cities all over the country, and even all over the globe. it will be...an astronomical compendium of public transit knowledge, all in one place!!
