Due to some unexpected travel, I am going to replace Jonathan McDowell as the online speaker for the Kalamazoo Astro Society next week. I won't lie, it's pretty darn cool to be the substitute Jonathan McDowell for anything, really!
But yeah, sorry, Kalamazoo. I don't have everything in orbit in my head (and a public database) like Jonathan does! But I do have stories of trying to offer donuts to silent SpaceX employees at a middle-of-nowhere grain farm, so hopefully that'll be an ok swap.
