It would depend on if I had any expected expenses coming up, but most likely I would throw it all into Vanguard. I try to treat any windfall as "non-existent" and just invest it to let it grow.
Which is what I did when I received a small inheritance (4k) when my grandfather passed. Although he probably would have preferred I go to a baseball game, smoke a fine cigar while sipping scotch, but instead it might let future me go to several baseball games.
