This is our 4th trip, so we're not new to ABD. I've read all the info on the website. I discussed the Peru trip a little with past Adventure Guides. I know there are several folks on the board who have taken this trip, so I'm just posing this open ended question to see if there's anything I should bring that isn't llisted on the website or any other useful information you can offer. I know from reading past posts to keep my mouth shut during the rafting and to hold on to my backpack in public places, both of which are very important pieces of information but not something they would mention on the ABD website. Any other useful tips? I booked a pre-day too, so any recommendations on how to fill that time or any good restaurants would also be appreciated.
