If I had the advantage of the insight into Puerto Rico that I have now at the beginning of this trip I would have spent two nights in Arecibo instead of the nights in Hatillo and Manati. This would have allowed me to leave a significant amount of weight behind on the trip into Karst Country as it is known. If I recall correctly, and doubtless Father will correct if I am wrong, karst rock formations are limestone upon which time and water have had time to play. Depending on the region, they can take on pretty spectacular forms. In Puerto Rico, this means sinkholes and related structures.
As my skin was at the bubble stage of sunburn, I wore my long-sleeved jersey to protect my forearms. Otherwise, it would have been the turn of the red Star Trek jersey I wore in the Mango Cycling interview.
I set off up hill along relatively gently rising farm roads before joining a slightly bigger road which had the advantage of more carefully thought out hills and a wonderfully wide paved shoulder. This brought me to the Cavernas de Rio Camuy. At the gate there was a list of vehicle fees which only got as small as motorcycles. When I rolled up, the man jokingly inspected Leonardo as if searching for stowaways. There was no charge but he handed me a numbered ticket the significance of which I wasn't altogether clear on.
The Cavernas de Rio Camuy is run by a profit-oriented company which is a pity as it could be done so much better. After buying my entry ticket, I found out that the numbered ticket was they order in which I would get on the trolley to go to the actual site. At the time I arrived, this involved an hour's restless waiting, thankfully in the shade. Had the company been more enlightened, it would have some panels explaining the geology of what we were about to see.
My trip back to Route 2 led me onto quite a small road that apparently doubled as a dump for the locals. I could hear a car behind me as a big truck appeared in front of me. I decided the best course of action was to get off the road and into the concert gutter as there was barely enough space for the two of them! The truck and car sorted themselves out. As he drove past, the young man in the car gave me an appreciative thumbs up in thanks.
