This cache is a take off from one I did in Winnipeg.
In order to meet the Mensa Cacher Challege, you need to have a day where youmust find 5 puzzle caches and at least one must be a difficulty 3.
Please feel free to sign the cache at any time, but only cachers who have completed the challenge may log online. Failure to follow this may regretfully be the reason to have your log deleted.
