Built by the French in 1755, New York's Fort Ticonderoga has seen a few battles over the years. The intrepid team from TAPS visited to investigate, with the notable exception of one Grant Wilson whose absence was reportedly due to an illness in his family. We wish you and yours well Grant, and I hope your absence won't take too much away from the team's findings.

TAPS is back in Ghost Hunters' 100th episode. They really wanted this season premiere to be special and actually made it a 2-hour event hosted by Josh Gates where our favorite Ghost Hunters talked about their investigation and took questions from a live studio audience (Is this leading towards becoming "Crossing Over with John Edwards"? Would you really be that surprised?)  Dustin and Barry from GHI join Jay, Grant and the team to investigate Alcatraz Island in San Francisco.

The GHI team heads to Montego Bay, Jamaica for some fun in the sun — wait, no… party all night? Closer. If you said, "Walk around a large empty building until the sun comes up," then you guessed correctly!

The Duran Sanatorium was built to treat Tuberculosis patients but in the decline of that illness it was repurposed a number of times, including use as an orphanage and a prison.

The team heads down to Costa Rica and investigates a notorious island prison, Brandy called it Costa Rica's equivalent to Alcatraz. Dustin didn't make it to this investigation so Barry took over as second-in-command.
