I posted the following on the Yahoo Group site:
For the 4th of July event, the team is in need of 6 walkie-talkies. The people directing traffic from the 3 entrances to the parking areas will use them. If anyone has walkie-talkies that can be used for the event, please reply ASAP.
They will be returned to you before the event is over.
If we cannot find walkie-talkies to borrow, we will have to purchase them.
