Tom, actually found that out just a few hours later. I received correspondence today from Chuck Darnell confirming that he has Snowlball. While the original Intent was for Snowball to be donated to the GSL Museum , it's my understanding that due to it's fragile state after many journeys while not being properly cared for, Dave Mikrut decided it best that it stay with Chuck, as he had the made many repairs and fixed the issues that occurred during transport. Dave and Chuck were close, so it is in a good place for sure. I know that several of the participants still build, bit I am not aware of the status of all of them.
I just got this picture today from Chuck himself. SB in upper left corner.
