I like the Northwest. Since we may not have a tent why not do a tour instead of a rally. Meet somewhere for a night or two and then ride to a new place each day after that. It wouldn't have to be a group ride, it could be several small groups or ride at your own pace to the next nights destination. We could see a lot more country and people could join or leave the tour at each nights destination. If you have two days that's great, if you have five days you can see much more.

Just a thought but it might be fun.
