I just put it on my boots too. I've seen someone just tie a tampon around their ankle using a little piece of string, then they just put it in a baggy and throw it out when they get home. Seemed to work well and be a good idea. They make things you can buy too that I've seen, but I've never bought any.
In your anger do not sin; when you are on your beds, search your heart and be silent.- Psalms 4:4
