I read many of the logs that are posted on my caches, but sometimes I can't read all emails. If you find a problem with any of my caches, please post a "Needs Maintenance" log. Logs of that type are filtered into a special inbox that gets 100% read. Thank you.
For all of my caches placed within the Mackinac State Historical Parks managed areas, a permit has been filed and paid for each year.
