Here's the setup: I'd like to hide a cache which contains a question (Canadian history). The finder takes home the question, does the research, and emails me back with a simple answer. I email /return a set of coordinates in exchange for the correct answer. These coords reveal the location of a 2nd cache which houses the prize and other swag.
On the online form, does this sequential caching correspond to a multistage or a mystery/puzzle category?
Thanks for clarifying!
