1. Weather is highly variable. It will probay be chilly in the morning, hot for most of the climbs and chilly at the top. But you never know, it could rain or snow.

2. Definitely at the tops of the climbs. I think there was one at tom's place, people handing out bottles (although maybe not neutral) at the bottom of pine creek. And an aid station at 6K feet (i think) on the south lake climb. On the second day there are two aid stations on on the last climb. That's lay year anyway, haven't looked at the emails for this year. My wife will likely be driving around giving neutral feeds as well.

3. They record numbers at the tops of climbs. They are pretty good about getting everyone. Not many other opportunities to cheat.

4. Yes, but there aren't many, and some of them ar during neutral portions. The most annoying one is the one at the top of Lower rock creek and the 395. You really want to stop at that one anyway, since it's a highway crossing...

5. Fast, mostly good roads. The top of rock creek is a bit rough. Don't think there are any cattle guards that I can recall. The glacier lodge descent Ive averaged over 40mph on the 10ish mile descent, with peak speeds over 50. It's straight and steep and smooth but there is a sheer drop on the right side when descending. I like to ride it close to the centerline.
