I could have sworn that someone posted something about a seat pack extender rod that would allow use of the Aqua Rack.

Repost^n?

Anyhow, I take my Camelbak on longer rides / days. Some recent examples of how I use or don't use it:

- 82 mile training group ride, brought it, plus one bottle (refilled bottle once)
- 60ish mile training ride with my bro, didn't bring it (two bottles, refilled once)
- 50+ miles, with a few hours watching a race, brought it plus a bottle for my lazy bro who only has one cage

I use a Camelbak on longer rides, bottles on shorter rides and I am working on strapping one of the big Gatorade coolers on my bike for the next century.
A little hot on the back in the middle of summer but I like the Camelbak. I use the 2.0

There's a good mix of that too. Moving here 10-11 years ago from Southington was like culture shock. Fortunately I live a couple hundred yards or so from the Willimantic/Mansfield line, so it's not too bad where I'm at.
