You will get some here that will point out that your question has been asked and answered a zillion times so you might want to narrow down your question. I agree with them to a point, as forums are here for partly just entertainment and communication. Otherwise, one might just tell you to go read a book with the information in it - then we might not use this forum much though.
So, when you goin? What kind of equipment do you have or have access to (or experience with)? Questions like those can help you get what you need.
Glad you are planning the trip. That is exciting!
