Hello:
I lived in Luang Prabang and Vientiane for 3 years. A few years ago, I forget what season it was, but teams disappeared only to be seen connecting somewhere in Singapore, and Vientiane was a possible location, so I e-mailed Peach and went to the VTE airport on my motorcycle to see if anyone was on that flight.
If people want to PM me any pictures, I'll try to help you all out figure what/where they are. *i do not have any pics now- I’m in San Francisco. I haven't watch the Amazing Race for a long time (most seasons just have felt too gimmicky), but I always would watch episodes of places I lived/places I really want to go/really unique locations (I loved the Shetland Islands episode ... and most non-Ontario legs of TAR Canada). I hope they treat LPB right as the utterly beautiful and gorgeous place it actually is. I'm not always logged on, so sorry if I'm slow.
Given how slow the Laos government is in issuing permits and whatnot, I wouldn't be surprised if they tried to do 2 legs here. The only places that I think could support a leg are Vientiane and Vang Vieng; things are too under-developed in Phongsavan to warrant a trip to the Plain of Jars. I could also see them doing 2 legs in LPB as there's enough to do there.
