Hi Steve,
I saw the sectors: EXTREME/ADVENTURE SPORTS and ENDURANCE SPORTS to which I belong a bit. I'am an adventurer and explorer going on expeditions. (and I know 500 adventurers personally)
So, wondering, if it would be possible to add those sectors as well:
a) perhaps modify EXTREME/ADVENTURE SPORTS to OUTDOOR/EXTREME SPORTS (for surf, red bull stuff, running etc)
b) and a new sector: ADVENTURE/EXPLORATION/SCIENTIFIC EXPEDITIONS
which is more appropriate.
