I am looking to do my first week long tour across Missouri this June. Currently I don't have any touring specific gear, though I do have a good touring bike equipped with a rack.

My questions are these:

What is a good inexpensive set of panniers? It does rain some in Missouri in June so it could be possible that I may be riding in some rain. I don't have the option of moving the dates of my tour due to inclement weather, so some water resistance would be a plus. I know I could always wrap all my stuff in plastic bags inside the panniers; I am not against going this rout to save money.

I will be camping outdoors along the way; what are some good options for sleeping outdoors? I need some sort of bedding and shelter but again, I don't want to spend a lot of money. I know that one can buy touring specific tents and sleeping bags that are small and lightweight, but I also know that these can be very expensive. Are there any good alternatives, or maybe some good inexpensive ones?

What would your bring along for a week long tour in 60-80 degree weather?

This is my first real tour and I'm not sure how much I will be touring in the future so I don't want to spend a bunch of money on gear that I may not use much. I'm just looking for some options that will get me through this tour semi-comfortably so I can get my feet wet and see if this is something I would like to get more in to doing in the future. If I knew someone who had some of this stuff I would just see about borrowing it but I don't, so that is not an option.

Thank you for any help you can provide.
