Sure thing brother, I'll be happy to help, it is really quite easy.
And for rain capturing, a simple gutter around the dome should work well, perhaps you can try to capture the due as well (can be also easily done with some cheap material).
Anyhow I am here for you if you need any help.

Yeah I have to admit, if you will not have much time then going to Goa is probably the best choice, you can do even 1-2 weeks there, very easy to get there, no "india shock" to handle and you can start having lots of fun right away...

For the other parts of india I would dedicate at least 1-2 month, In my opinion lees then that might not be worthwhile, as there is usually a certain shock curve for new visitors on the first time there.

So It takes a bit time to get used to it...and india lets you have a "smooth landing".

"Nature Parties" is just a way people call here "raves", it still has a certain underground vibe to it here, the parties are usually secret (except the big ones), you get the directions couple of hours before the actual party, and getting there is a journey on its own, as usually they are in remote places in the nature, where nobody can hear :)

Mo:Dem looks awesome...WOW what a location...WOW
