I doubt I'll be out in truly icy conditions. And, I'd like to stay with my Keo/Look cleats. Thus, SPDs are not an option right now. And, regular shoes and platform pedals aren't really an option either as I'm first going with all options related to wearing road shoes. I have a couple pair of mtn bike shoes/boots with SPDs for my mountain bike.
I'll try the plastic grocery bag method also to see how it works. Thanks again for all the comments.
Edited to add: I won't be riding thru any cities -- mainly riding in the country on backroads and such. No commuting, only training rides of 20 to 50 miles. See this post for an idea of the areas I ride and similar:
