It's an interesting way to spend time in Bali.. I understand that you live there (after reading your post) and I think that most tourists would choose to spend time on a beach instead of camping at the lake. It is indeed beautiful there.. I can imagine that there are lots of mosquitoes as we also have them here close to rivers/lakes.. but luckily here you can't get sick from their bites..
I'm glad to hear that you negotiated lower price at the end even though I understand your point about being racist. On the other hand I think it's their way of making money but I'm still sorry that you have to experience that.
Thank you for sharing your video and I'm looking forward to seeing more videos from you :)
