A lot of the engines were on makers trolleys, while the majority were fixed on trailer beds. Fuel was almost universally propane, and I understand that a local company had an arrangement to supply gas to the show in exchange for some free advertising around the site. Similarly a local company has supplied engine description sheets for owners to fill in, which had the company name etc on the top.
The visiting engine owners were having a great time, and I was able to wander amongst them and ask questions without problem. There was no 'engine snobbery' that we occasionally see in the UK with owners of the rarer engines and I was made to feel at home by all the groups or individuals that I came across and stopped to talk to. It was a very good atmosphere to visit in.
Not many engines had loads on while running, and this made them possibly less appealing than they would have otherwise been. In the UK we tend to have engines running at their rated speed and load, even if it is not continuous. It didn't detract from the interest of looking at the engines as there were so many new models and makes to see, but apart from a large sawbench I didn't see much else in the way of a loaded engine.
