Did many allnighters in the darkroom in my youth. No regrets, and miss some of it - watching the print in the developer tray, dodging and burning - but I prefer things now. Maybe this is the camera to bring: Sony's newest all in one weather sealed superzoom, rx10 iii. https://www.dpreview.com/search/?query=rx10&product=sony_dscrx10iii It's a 2+ lb brick with a horrible interface, and expensive, but the reviews all say the pics are good, versatility is excellent with very wide zoom range and quality lens, and it's weather sealed. Perfect for the tank bag. Regarding tripod hassle, I'm working on a slick setup: Wolfman double end opening dry bag strapped to the top of a pannier. This would stow the tripod in a weatherproof container, requiring only seconds to take out or re-stow. But I appreciate the advice to just leave it a home for this trip. I'll try it on my annual BRP and Smokies run in May and see how it works out.
