What's exciting about a Charter Bus?

I saw a charter bus roll up to church this morning and had that great feeling of anticipation and excitement that charter buses always stir in me.  I thought a bit about why:

1.  It cost a lot of money, so somebody, somewhere really cares about the reason it's here.

2.  It probably came from somewhere pretty far away (usually).  A group of people have been on a journey together.

3.  I think about the luggage compartment: what are they bringing with them?

4.  Drivers are usually pretty cool people.

5.  The people on the bus have learned or are learning how to live with each other.

6. There are probably lots of new experiences represented on the bus.

7.  From time to time, new people get on the bus.  Others get off.

8.  The people on the bus don't always know where it's going and it doesn't seem to matter.

9.   We represent a destination at that point.

10.  The people on the bus are there for a reason.

If you chartered a bus for your ministry, where would it be going?  Who would want on?  Who would want off?  Would you fit my profile of "most drivers"?  Why would people get on it?
