Infield at a track is nothing that I would want to do today. Back in the Grand Prix and Can-AM years I worked for Facility Services at the Glen,picking up trash. We could not work during the actual race due to the possibility of blowing debris. Having a full access pass was amazing, went every place met a lot of drivers and crews.
Of course back in the seventies security was close to non existent.
Anyone remember the Bog? more than one Uhaul truck met its demise there!
