It could be a considerable amount Joe, Some countries in region 1 are small. I Europe you can easily drive thru 5 countries in a day, And if you are in the Balkans area you can do it in half a day. For VHF its very common for high ground suitable for contest operation to be just over the border. to give you an idea, it would be the same as any US hams having to put the state prefix in font of their callsign if operating outside of the home state.
