It is going to rain, they say, on Saturday. Saturday is the Indianapolis Tour de Cure which I am riding in. I've no money for rain gear between now and then - so I will just plan on getting wet like I did this weekend (which was kind of refreshing actually).

Of course I need to take care of this, but I've little budget for yet more bike stuff for awhile - nor do I want to buy junk either. What is the most affordable option for a summer-weight rain jacket? I have looked, but I don't know enough to know what is a good price for a decent jacket, or a high price for a c%#)py one

Thanks in advance!
