Questions people actually ask
- What can you do in Thornton for free?
- pARTy and Rigsby Revisited: The Arvada Center Turns 50, Westy Fest 2026, Fireside Chat with Ken Salazar, Trick or Treat Street in Olde Town Arvada, and 1 more. Full list on this page.
- Is this list current?
- Yes. Neighstradamus rebuilds from a live Denver events feed daily, and past events drop off automatically.
- Are these events free?
- Every event on this page is free to attend.
- What neighborhoods does Neighstradamus cover?
- Neighstradamus splits greater Denver five ways, spelling the only word he says: The North Pasture (N), The Eastern Flank (E), The Third Eye (I), The Golden Gallop (G), and The Haunches (H). Every neighborhood from RiNo to Castle Rock lands in one of them, so the horse always has somewhere to point.
- How do I get one good recommendation instead of a list?
- Go to the homepage, point at your part of town on the map, tell him who is asking (weirdo, family, hot date), set the date and budget, and pull the lever. Or let the horse decide everything.
