I live in Karlstad a town in just about the middle of Sweden with one of our great lakes just outside my doorstep with an estimate of about 5000 shipwrecks and a few downed airplanes
A one hour drive takes me to a region full off undived old abandoned mines just begging to be explored. 2 h takes me to the Swedish Westcoast and 3,5h takes me to the Baltic sea with its brackish water and wellpreserved wrecks.
The one thing i miss is long unexplored natural caves but you canīt have everything can you?...
