Natural Gas buses are not better than Diesel Buses. Dave Dobbs reports the scoop on natural gas buses.

What is Bus Rapid Transit? BRT includes any or all of the following:

• A dedicated lane or separated guideway for the bus (so the bus isn't slowed down by auto traffic).
• Devices that keep a traffic light green so the bus doesn't get stuck at a red light.
• Buses with low floors to make it easy to get on and off.
• A limited number of stops.
• Train-like boarding, where passengers buy tickets before they get on the bus.

  All of these together make the bus act more like a train, without the big infrastructure costs of installing a train system. Of all these features, the first (a dedicated lane) is the most crucial. If the bus is stuck in car traffic then there's barely any real benefit over a regular bus, or a private automobile. (more on BRT...)

Taking a BikeE on the bus. writes: Here's how to get a BikeE onto a Capital Metro bus rack:

1. Turn the steering 180 degrees--makes the wheel base shorter.

2. Put the rear wheel in the well reserved for the front wheel.  In other words, use the movable restraining bar over the rear wheel instead of the front.

3. The front wheel still will not fit completely in the other well, but enough so that wrapping a bungee cord through the rim and around the well supports will keep it from inadvertently jumping out.  

4. When maneuvering the movable brace over the rear wheel, tilt the bike slightly temporarily toward you so that the brace doesn't strike the derailleur--once in place return the bike to an upright position.

I've used the bus now maybe 20 times and have had no problem.  (I do take my flags and panniers off, although I think one could leave the panniers on--I'll have to try that).
