I have discovered that it might be a good idea to add some over the counter cold medications to your first aid kit because they can be hard to come by, especially here in Ohio. It is a problem now because people are buying over the counter meds to make illegal drugs in meth labs so you can't buy a lot of cold medications unless the pharmacy happens to be open. If you need them after hours, you are just plain out of luck. I found this out when I needed some last week and it was late at night and the pharmacy at wally world was closed. Only thing on the shelf was those neat plastic cards to redeem at the pharmacy for cold medication. Once again, the bad guys are making it hard for the law-abiding.
