I saw my first Fer-de-Lance snake in Puerto Morelos, Q.R., Mexico a couple of weeks ago at a small zoo and conservation facility. They found it on the premises (jungle) where visitors walk and put it in an aquarium for display. Fortunately, they are active only at night. The zoo rescues crocodiles, snakes, and all kinds of birds and animals in the Yucatan including hairless Mexican dogs (which feel like pigs when you pet their skin and are the sweetest, most gentle dogs).
Cool. That's one species I've never seen in person...behind glass that is. Deadly to say the least.
