Just make sure you have plenty of water to drink and fresh batteries for your camera. I don't think much is needed for a day trip. I'm getting excited as well I can't wait to get out there and nail down a camp site and get on some trails.
The good thing is you guys will be able to get information on where we will be at in advance. My original plan was to post the info up Wednesday night which was pretty short notice. We will have to have an emergency back up communication plan just in case someone is in our spot. I highly doubt this will happen considering I will be getting there Wednesday but you never know.
