Sometimes I feel so old I think I pre-date bows and arrows. Having said that,my biggest fear is that people become too dependent on modern technology and electronics. Ain't nothing wrong with GPS and stuff like laser target finders,but let's not forget how to plot a course with a compass,or how to put iron sights on target and mentally allow for distance and wind.
If it comes down to everybody is fighting blind with fried electronics, we are going to be in the hurt locker.
