Beautiful, Philadelphia, the City of Brotherly Love!
I found a slightly burnt and mummified box turtle in a furnace parked on top of the heate exchanger, no cooling on this one. The owner said they always wondered where that box turtle was hiding. The poor thing fell down a floor vent and found his way to his doom.
The place was a bit of a dump, I was wondering how they did not notice a warm dead turtle smell the thing was about the size of a series 8000 Honeywell.
The turtle was probably like an air freshener, "Gee honey you need to get a refill the smell is gone".
