Raised garden:
Kayak rack:
Work benches/storage:
(Don't judge my cluttered garage, that's why I built the benches, it's a work in progress)
And I've still got two pallets left! Plus some random bits and bobs.
Edit: removed some doxing info
Oh, I had almost no doubt of that! But just in case you inspire others, probably something to keep in mind.
Haven't done much with pallets myself, but from my experience the chemically treated pallets are kind of obvious. Does that match up with your experience? That is to say, if it looks like untreated wood, it probably is untreated wood? Not that I'd take the risk.
