I think I will make some BITs to go along with my Munzees. BIT on one side, Munzee on the other. Laminated or something. Either in a container or not. OCNA minimum limit is 300' feet. Munzee is 150', so you can place a BIT for every two Munzees on a trail. As they say in Munzeeland...Grow the Map! No pen required.
A friend has an iphone and she complains that there isn't a specific app for OCNA. If I do BITs with the Munzees, she can just use the Munzee app, then scan the BIT to get to the webpage to log it.
Since I do several scavenger hunt things, does that make me a SightMunzee CacheBoxer? Sounds like a sport where I need protective headgear.
