/ The black bear used to be one of the    \
| most commonly seen large animals        |
| because in Yosemite and Sequoia         |
| national parks they lived off of        |
| garbage and tourist handouts. This bear |
| has learned to open car doors in        |
| Yosemite, where damage to automobiles   |
| caused by bears runs into the tens of   |
| thousands of dollars a year. Campaigns  |
| to bearproof all garbage containers in  |
| wild areas have been difficult, because |
| as one biologist put it, "There is a    |
| considerable overlap between the        |
| intelligence levels of the smartest     |
\ bears and the dumbest tourists."        /
