I found the general impression in DVFC a little 'awkward'.
First I went through a lot of (friendly and informing) emails, but I had to stress my 'reputation' as a birdwatcher / researcher. I was a researcher at that time, but not on birds. So I told a rather vague story about me being a researcher, hardcore birdwatcher, member of the Oriental Bird Club etcetera. Not to boost my ego, but just to show my credentials so they would let me stay there!
Second, when in the field centre, there was hardly anyone there to introduce us to the site. Yes there were signs saying you weren't allowed to go out on your own, but I never planned taking a guide and was happy they didn't offer me, too! There were a lot of people (employees of the field centre?), with big pick-ups using them to go from one building 100mtrs further to another... We were walking the whole day in the tallest and oldest forest in the world searching for pittas, and these guys were smoking sigarettes and driving their pick-ups and putting up signs you shouldn't enter the forest without a guide... Not the situation where a stubborn guy like me would obey their rules!
That was the awkward thing: We were about the only guests, going on the trails from 5 in the morning 'till dark, and nobody looked after us or knew where we were hanging out. They knew we would show up for dinner around 7PM, and as such, dinner was on the table at that time. (note that shared dormitories are approx. 500 mtrs away from the dining hall, this is quite far for tired legs at the end of the day!)
One night, there was rumour about a night drive by a (German?) young researcher who was studying herps (mainly at night, so we didn't often meet eachother at the field centre). So we agreed on joining and it turned out there were some other (Malaysian) tourists that day wanting to do the same. The driver and guy with the big torch seemed experienced in doing night drives, and we did see some cool stuff (though not the Marbled Cat - kind - of - stuff).
