Thanks for your ideas ,
not traveling by car , and if I was I would probably bring my rice cooker , or put the soup can on the dashboard and "solar heat" it
The Hotels I stay in do not have an in room microwave normally , and being able to have something warm without much trouble would be nice ,
Part of this is when I am out of the country and want something "safe" to eat , I am not the foodie that will eat anything off a street cart , I have been sick too many times from bad food ,
The ziplock bags would work if I cannot find another simple solution...
Keep those ideas coming , Thanks again
