Abby Went to a Party

A few weeks ago, Abby went to a friend's birthday party.  They went on a bus, thus they weren't driving around while or after drinking.  Myself, I don't drink, so I don't understand this concept.

The next week or so Abby was invited to her Mother-in-law's birthday party.  I thought this time it was st petersburg limos that they rode in, but it turned out to be another bus.

Sounds like everyone had a great time.  I cannot imagine having open containers in a vehicle, normally that is against the law.  However, a party bus must be exempt from this rule.  Have you ever been on one of these vehicles?
