David is a fabulous guide. I did the 17 day overland adventure trip in Alaska and had the most amazing time ever. David is very knowledgeable about Alaska and is good at pointing out new things to try. Without his encouragement I never would have gone ice climbing but I can't imagine the trip without that added adventure. I recommend that everyone sign up for an Infinite Adventure trip with David. You won't regret it. I am already saving up for my next trip with Infinite Adventure and David.
