When the wife & I drove separate Merkur XR4Ti's up to the All-Ford Nationals in Carlisle, PA every year, we stayed in touch using 2-way Cobra walkie-talkies. These worked really great! And I think my set, since it's probably 8-9 years old, has a range of only 2-3 miles. But for only a couple of cars, it's all we needed back then. And probably still takes care of a larger group today, as long as you're not trying to make contact with someone who's remotely located from your spot.

I'd encourage anyone planning on making this trip from any & all points to go out & purchase a set of portable 2-way radios. Expense is less than $100 and can be used for many activities outside of this event. Roberta & I have used these at car shows, county & state fairs, concerts, whatever.

Just be aware that you're using a device on an open channel that can be scanned by anyone out there with a similar device. Roberta & I occasionally found our conversation interrupted by someone with a scanner unit that could pick up our frequency. The truckers nearly all have a scanner unit and could listen in on your conversation. And if I was one of them out there on an open road by my lonesome, I'd want a scanner too to be able to reach for help or pass along a message.
