I used to use paper maps too.

In my case, was exposed to single shots at an early age while riffling through my dads girly magazines. Happened onto an Old West magazine that had an article about long range shooting in the old days. Think the bug started there and lay dormant till I saw an ad for Hagn rifles and actions for sale by John T Amber. Exchanged letters with Amber about the actions but couldn't come up with the money. Then the Rugers showed up on the market. Noticed an ad in Guns and Ammo about the Coors match at Golden.  Was working on a power house in Colorado, met Ron Long and his Dirt Ballers. Has been a lot of fun and a lot of frustration. Never get tired of single shots.
