I was thinking about this tonight because of a 'thing' in vault 92.
Mines set close together will trigger eachother, so a line of mines set in a row with a trigger mine set in the right place could maybe do a lot more than a few seperate ones...
Or a row of mines on each side of a tunnel, with a single mine in the center of the array.
~I'm toying with this at the back of my mind as I find my way south to Arlington Library.
