With miles of open river to explore, Alex and Nico use twin "Argo" six-wheeled all- terrain vehicles to shuttle back and forth to the river. The Argo is basically a two-person river assault machine that drives like a tank over rocks and stumps, and even swims across the river on demand. After a 45-minute, herky-jerky ride through the lenga forest, trust me, you're more than ready to stretch your legs and wear your arms out on big trout.
