Well, let's see. I hunt by still hunting or spot and stalk, both of which have been around a lot longer than 20 years. I still use a handheld compass and map, both of which have been around a lot longer than 20 years. I don't have a smart phone and don't want one. I do my scouting by putting feet on the ground so i don't use satellites and "apps" for that. I use a recurve bow that has been around a lot longer than 20 years. I use the same rifle I got when I was 13 (I'll be 53 on my next B/Day) so that is longer than 20 years. I have a 1970 Ford pickup I still putt around in.
Do those count?
