For the fourth summer in a row, Explore.org's highly popular and completely riveting Bearcam is up and running again. If you haven't had the pleasure, that's a live feed from several HD cameras set up around Katmai National Park in Alaska, where hundreds of bears gather this time of year to catch salmon swimming upstream. Among the things you might see: showdowns for the best fishing spots at Brooks Falls and mama grizzlies tending to their impossibly adorable cubs. The cam is good inspiration for planning a trip to Katmai or for planning a weekend staycation glued to your laptop.
