Thanks! I ended up moving away from the valley several years ago, but missed it so much that I had to come back.
I was actually going to PM you the link if you hadn't seen it on here as we've discussed my area over the years. There's much exploring to do in the HC Wilderness and a lot left to be discovered!
I probably have around 70 nights in the Rainbow and there's only been a hand full of times where I've been slightly disappointed. I incorporate my trekking poles and only bring two ti stakes so I believe that skipping the four stakes on the sides reduces the strength. Rain is never a problem except for a little bit of dampness that comes through the mesh in downpours. Also I've noticed that when pitched on a surface that has a lot of small gritty dirt material; in heavy rain some of the that will dirt can cake the mesh with wet dirt and water. The water that actually gets inside the tent is usually minimal.
While you can position the rainbow in heavy wind to improve stability, I've learned that it proves useless in heavy SWIRLING wind. It isn't built for central Iowa...
See example from my CT trail journal:
I had to quit writing several times as one of my tent stakes came out of the ground causing one whole side of my tent to slap me in the face as the rain began to fall as well. The wind is now very intense. Right now my tent is staying up right with the help of 6 big boulders. I’m cold and my nose won’t stop running, but I’m still in high spirits.
I’m confident that when I leave my tent before the sun rises that the sky will be clear and the wind calm. Fourteen hundred feet to the summit then it’s down to Creede for the remainder of the day. I now zip up my bag and get ready for hopefully a quiet night.
August 14th – Day 21
I could have not been more wrong. The first time I checked my watch it was midnight and I still hadn’t got any sleep. As I tossed and turned the wind pounded against my tent causing very loud flaps, whips and cracks. Every hour or so I’d get up and check the sky only to see an overcast blanket. I wasn’t in a particularly sandy area, but when I turned on my headlamp I saw a thin layer of sand on the tent floor that obviously got there through my “no-see-um” screens.
The cold wind crept through my tent as I curled up inside my bag. Around 3:30 am the wind sped up on the vestibule side of my tent. I used four volleyball sized rocks on each of the four corners of my tent to support its tautness, two rocks sat on top of the only two stakes.
Around 4:00 am the wind go so intense that I started to get hit again by the inside wall of my tent. I remedied the situation by propping one of my trekking poles vertically along the vestibule side wall of my tent. It was probably around this time I decided not to summit as it was already around the same time I was hoping to start the climb. Six rocks and one trekking pole later I started sleeping decently and awoke at 7:00 am to a sky full of clouds.
