I totally agree, the happy hour story explains it as it is. People are more social when on the road and can't help but come over and say hello. Conversations generally start with where are you from and where are you headed, after that we just talk and talk and talk. We have met many top people and heard some great tales. Jess often cooks up some nibble food and I am the one in charge of chilling the refreshments. Which reminds me I have a job to do.
Just pointing out that happy hour is not only a sociable gathering but also a source of useful information. Usually you meet people who have just travelled the road you are about to embark on and can give you the latest updates. They might include the condition of the road, something to stop and look at along the way, which roadhouse is trying to rip you off (fondly nicknamed Ned Kellys) or caravan parks to avoid. On that subject, AVOID Bellhaven Caravan park at Heatherbrae NSW. It houses some very very, and I mean Very, undesirable permanents.
