I would think, from a safety standpoint, using APRS at our meets would be a home run. We can see where the trail guides are, we can plan what trails to hit at what times... pretty cool things that can be done.
I get that right now, we're dinky but if you think when we have lots of members and say, we're doing a meet up at the trails (that we have to map yet) in the Northern Highlands, being able to see what groups are where would be awesome. This way, if a group needs help we know where to lend help just by looking at a map.
(This is where I saw it first)
