I'd like to split the cost of some guided birding for a day near Chiang Mai and or 1-2 days near Bangkok. Are there other ways to find people? Specifically Chiang Mai all day November 27 and/or Bangkok December 11 and/or 12? I've found friends for a couple of past birding trips in Central America but not this time, and I'd love to find 1-3 others to split the costs via one of the two birding tour companies I found or another that reduces the cost, and shares the enjoyment!...In the future I'd love a way to find people to do the same when I am traveling with non-birders! Thanks in advance...traveling from California, hablo espanol et un peu de francais aussi! Vivienne
