I was reading the Toronto Star online edition this morning and this story caught my attention. This fellow east Toronto couple found a snake in their house for the second time. They found a snake a month ago while renovating a bathroom but it slithered away. After a month they recovered the initial visitor and within 2 weeks they found another one (apparently a quite resilient one that survived the wash cycle of their washing machine). The Star article does a good job of highlighting all the freaky facts of how far/long snakes can live if they escape from their owners. Given the close proximity of housing in Toronto it's a little disturbing ;o).
One interesting thing the news story links to is the husband's YouTube page where they've done a really nice job of documenting the hunt for snake #1. I hope they got some footage of this new visitor and continue to document their snake saga. It's kind of fascinating.
