I have ventured many of them solo. Filmed a couple downhill mountain bike videos on them actually, if you're interested. They call this part of the world the "mountain bike Mecca."
He's a crazy outdoor adventure marathon guy who like lives and survives for months at a time in the middle of nowhere until eventually finding the finish line or however it works. So, individually, yeah, we've spelunked many of them. Together, however, unfortunately none.
One dude on here said something to the affect, you guys at a table together? I would've loved to be a fly on the wall for that conversation. Still one of the nicest things anyone's said to me on here.
