Hey TMP this is the first time I've read your original post and it certainly strikes a chord.
I have done gascid quite a few times. By the way, I find it equally amazing (but in different yet similar ways) with nitrous on mushrooms and other psychedelics. If you've never tried it with shrooms you've missed out
So anyway I wanted to share my most amazing gascid experience. I was out tripping in the woods with my ipod with a pack of nos chargers in my bag. I had previously had a similar experience on shrooms/nos and knew it would be good.
Anyway, so I sat down plugged my ipod in and did some nitrous. It was one of the most amazing and awe inspiring half an hour or so of my life. The trees came alive (most remeniscent of Treebeard in LotR), they were living and moving entities. I have found that in my nitrous space, the nitrous itself only opens the doors fully with music it 'likes'. After several tracks of amazing nos trips I played one and nothing really happened, but one of the trees beckoned me with one of it's branches, like an arm/hand to play a decent track! I have found this other times as well, like only certain music works somehow.
If I could afford to buy crates of nitrous I possibly would, but your story has definitely made me appreciate that it would really not be the best idea.
Good luck for the future The Merry Prankster
P.S. I would dearly love to have a go on your 'ship' :D
