Snake phobia

Costa Rica, a country merely the size of West Virginia, contains 8% of the world's snakes. I will soon be there for 6 weeks and have a massive snake phobia. I currently live in NYC where the chance of encountering a snake is fairly slim. (exception: my friend's sister in the Upper West Side found a black snake in her bathtub; apparently a neighbor's escaped pet)
CR is home to some of the world's deadliest poisonous snakes: Bushmasters, boa constrictors, coral snakes, fer-de-lances. I am convinced I will be one of the 800 people who gets bitten yearly in CR, so have studied up on what to do in case of a bite. Luckily, only 10 die and I think my odds are better than that
