Directions to get to Lake Tahoe, Nevada from Reno or Sacramento?

I'm sure there are bus services that go from Sacramento to South Lake Tahoe, as the previous poster said, provided by the Casinos. However, the driving time from Reno to Tahoe is A LOT less than from Sacramento, and I believe its even cheaper to fly into Reno than it is to Sacramento, so if you aren't planning on doing anything in Sacramento, I would suggest flying into Reno.
