At Marfa Gliders in southwest Texas, every pilot has to bring a dedicated crew. (Watch "The Sun Ship Game" filmed at the 1969 contest at Marfa to see effective old school crewing.) A crew that is hooked up to the trailer ready to hit the road late in the day towards the last known quadrant. Poor cell coverage around here and very few suitable landout places. The ranch strips depicted on the El Paso aero chart are usually too narrow. The high mountains surrounding the Marfa plateau may block a radio call from a low sailplane working the rocks.

Some pilots land after sunset which is only permitted if you turn on your position lights at sunset. That's when you gotta have lights by the regs in the USA. No heartburn from me, just sayin'.
