Jesus was baptized in the Jordan River by his cousin John the Baptist. Today you can baptize your self for the cost of renting a robe and towel for $10. Personally, I think this is a little crazy, but who am I to say you can't be baptized where Jesus was baptized. You can make it a day event by having lunch and buying trinkets. Despite the freezing temperatures, there were quite a few people who were not going to miss this opportunity.
