Bears are not uncommon in New Jersey. It is believed that 2,500 black bears live in New Jersey. They have been spotted in all 21 counties. However, it is rare for a bear to enter Trenton. But that is just what happened in 2013. A young bear was spotted in Cadwalader Park. New Jersey fish and wildlife rangers shot the bear with a tranquilizer gun and returned it to a more remote area.
This bear was not the first bear in Cadwalader Park. A bear called Briar Patch was held in a cage from 1952 to 1983 for people to view. He was believed to be the oldest living bear in captivity. His grave (along with a stone monument) is located at the park today. http://www.trentonian.com/article/TT/20130714/NEWS01/130719787
