Thanks dubd!
I had a great time.
As to the field, they built that field for events, they don't "use that field". So with that understood,the physical layout of the runway is about the only way it can be to keep them out of the airport traffic and from over houses and roads.
Are there more suitable venues out there? Maybe. Are there any that wouldn't cause Frank to have to pack up an entire circus and move it to another town to host an event like FJ or TG? No
