None for thousands of miles!
In other news though... Ghana is the most impressive untouched bouldering mecca-wannabe I've ever seen or even imagined.
The area north of Techiman along the road towards Mole National Park (read: elephants and crocodiles hanging out in the same pond while baboons try to steal your stuff). Good camping, decent roads nice people.
So nice, in fact, that as I was trying to work my way through a low grade send... one of the Ghanians was kind enough to climb the other side of the boulder to give me a hand up! 'Crazy white people!!!'
The bouldering area is massive, untouched and kinda like the rock at Niagra Escarpment-though not as many finger pockets. It's easily 40km long- not sure how wide. There's a place called the Secret Rock Garden (or something like that- we didn't go). We spoke to an American Peace Corps worker- he said it was 3 hours of walking through endless bouldering potential.
Give it a go!
