Snakes and ladders

Went to the Butanta park today. It is a snake park (serpentarium) in Sao Paulo, which does a lot of research on snakes and also produces medicines.

Saw the Boa constrictor (of Harry Potter fame).
Most of the snakes were bored and only a few were moving.
There is an enclosure in the open, with a few Brazilian varities of snakes and then there is a museum which has a bigger collection, including some massive ones.
I was expecting to find an anaconda, but unfortunately, there was none :-)

The park is very well maintained and is also a fairly common picnic spot.

Today being Good friday, traffic in Sao Paulo was the lightest i have ever seen, and wouldn't mind seeing again.
Afterall, just a few days ago, i was a part of a world record wherein there was 221kms of congestion on sao paulo roads, and it took me about 2 hours for a 5km distance.
