I like the name that Alastair Humphreys uses, it's not 100% the same but the same direction: Microadventures

amazing, thanks for sharing. I was curious if there's already a name for this local travel. Micro-travel or planless-travel are close. Mini retirements are another term I like to use. I heard from the Pathless Path book (I think), which is traveling for up to 4 weeks - it's not 100% related, but it is what came to mind when I heard Microadventures.
