I prefer dairy but I’ve used oat milk in the past too. If you’re able to I recommend looking for oat creamer, it’s a little thicker. If you’re really keen on non dairy options I rate macadamia nut milk as the number 1 option.

If you make it over to Portland they have the Retro Gaming Expo! Lots of indie developers and they have a hardcore scene for old tech. Lots of vintage hardware with passionate programmers and game designers
