Those pics are great! A few friends and I put on a rail jam in down town Pittsburgh a couple years ago. we have ties to a local ski resort so we got our hands on a Techno-Alpin M18 snow fan (the kind used on ski slopes, mounted it to a trailer and hooked it up to a fire hydrant.
We had a foot of snow and two skid steers moving it. built two ramps out of scaffolding and had an awesome show. it.was the only snow in the area. good times.for sure!
