i am famously (for generous definitions of famous) not a fan of stacks, both as a constructor and as a solver, but i'm somewhat proud of this one. for imo the first time, both the stacked words and their crossers came out not too hideous and perhaps even fun! also i *really* feel like 38A has a killer clue (or maybe even a theme) hiding in itself somewhere, but i just couldn't figure one out for the life of me. hope you enjoy!
errata: changed 7D clue to one referring to the right word :)
