Back in the early 80's I was there for a long long stay, and rented an old wooden cabin with a thatched roof at Perseverance on a monthly basis(across the road from Miss Mary's). It was the rainy season and there were land crabs everywhere. One night about 10:00 pm, as I was about to turn out the light and get into bed, I looked up at the roof and there was a huge crab hanging by one claw from the thatch just over the mosquito net above the bed. I tried dislodging it with a broom, but it just hung on tighter. It was low season and I was the only guest in the yard and the owner's house was dark and locked up for the night. I walked out to the road to see if anyone was around who could help me, but the only travellers on the beach road were more crabs. Finally one of the owners daughters got up to go to the bathroom, and she got the crab out of my cabin (by whacking it harder with the broom!). For the rest of my stay at Perseverance, I never went to bed without checking the entire cabin for critters!
