While i was in high school i did the People to People program and went to England, France, and Italy
England- we were there briefly but it was a cool place to visit, the Tower of London and the London Eye were highlights.
France- we went all through france, i really enjoyed the Normandy area, Omaha Beach and the museum in Caen. Paris was cool. i kinda like southern france around Lyon and Nice.
Italy- was a blast. we stay primarily along the west coast. visited a bunch of small coastal towns, pretty cool stuff, and great food. went to Assis in central, and then Florence, and Rome before heading back to the US.
since i've been in the Army i've been over Alaska and the Cali desert. and overseas, i had a short stay at Manas Air base in Kyrgyzstan (former soviet union) and then been here in Afghanistan a year, and then had another brief stay in Ali Al Salem, Kuwait.
btw, if your in high school and interested in the people to people trip, apparently according to the website, i can nominate students who would like to go. if ur curious about it, pm me.
