I have tried to get my brother to share his Costa Rica adventures, but despite initially being excited, I think he is just too busy at the moment. I can't blame him for wanting to waste time in the country on a computer. Hopefully he will share when he returns. I will be flying down to meet up with him for a week in August.
About this time of the year in Ohio, I would start focusing on herping in the late afternoon/evenings and then roadcruising in the hot humid weather. This ended up being a very productive method at turning up some interesting pitvipers. Depending on your selection of roads, and persistence, you may happen upon a few of these...
Timber Rattlesnakes Crotalus horridus
and even more of these
Copperhead Agkistrodon contortix
We will try our luck a bit with roadcruising in Costa Rica and hope to turn up other members of Genus Agkistrodon and Crotalus.
