I'll throw this out as a possible drive during the weekend of the get together.
I think I can get us into see the "B" reactor at Hanford.
It was used in the Manhattan Project to end WW II.
It's not normally open to the public year round.
It's an hour drive out of Kennewick. (drive should be nice)
I'll be going when there is a lull in the gathering. TBD
If anyone is interested I'd need a head count.
