The problem with shipping them to yourself, as has been pointed out, is they'll arrive before you.

So the best option might be to have someone in FL take care of them for several days or a week so you'll have at least a day to get settled in and ready for them to arrive when you get to OR, then ship them to you. However, you'd have to be really sure the person knew how to pack them up properly.

If that isn't a possibility, you can take them in the car with you. I don't know much about how, but I know I've read threads about people doing it. You could probably do a search, or if you decide you are going to go that route, post a thread asking how and I'm sure you'll get some help.
