The Olympics will end in Beijing tonight, but the athletic achievements are just getting started for the Sousa family, which is setting out on quite the extreme sports excursion this week.

On Tuesday and Wednesday, three generations of the family, including 81-year-old Tony Sousa Sr. of Attleboro, will sky dive, whitewater raft, and tentatively climb a mountain in Maine.

Tony Sousa Jr., 50, of Plainville, and a former Attleboro and Seekonk resident, says the trip was initially planned for his son, Nick's belated 20th birthday.

Nick, who lives in Seekonk, is a junior at the University of Massachusetts at Dartmouth, and came up with the skydiving part of the trip.

"I decided that would be a great thing," Tony Jr. said. The skydiving is planned at Baxter State Park. The rafting will be on the Penobscot River. And as a hiker, Tony Jr. says he always wanted to climb Mt. Katahdin, the highest mountain in Maine, and which the trio will tackle if they have time after the other two challenges.

The mountain is located in the state park.

Tony Sr., a Norton native and veteran, is quite active for his age, having recently rode a giant rollercoaster in Las Vegas.

"I asked my dad, and he is all for it," Tony Jr. said of the Maine activities. "He'll do anything."
