A minor point, but there is one or more cougars/mountain lions in the Delaware,
Pennsylvania, New Jersey tri state area for the past 3 years. Tracks and
sitings have been occuring, with much disbelief, until someone caught it on
video tape near an elementary school.
I sometimes wonder about some of the odd
things Brin's transparent society cameras would capture. Rats, bears, cougars, and
other
wildlife in the suburbs. Could be the basis for a new reality TV series:-)
