You raise a very good point in that we need to be careful how we use technology like cameras.
Every year I get more interested in primitive things and less in new technology but you have to draw the line somewhere and accept some things.
In the purest sense is driving a modern truck to your hunting spot, heating your house or putting your deer meat in a deep freezer or not making your own bow and arrows traditional? Think about it; you typed your point of view using a "magic computing box" via this new technology called the internet. Original Trad guys did not have that.(understand your point and just giving you a hard time, no problems)
Simple. Trail cams are fun, something to do in summer and with kids, make cool pics to post up in hunting lodge or tell stories to with hunting buddies, lets you see if a buck you saw made it through the winter, survey buck to doe ratios, see if you got lots of coyotes around, see if have a hurt or diseased dear around, spot trespassers, fills your dreams, etc.
To each their own...Now crossbows, that is the devils technology, not cameras!
