I carried a single orange bumper. Laddie carried a white puppy bumper most of the time as he explored while I wandered around setting up blinds, but eventually he lost it. Maybe we'll find it another day.
We ran six blinds, distances 150-200y. Factors included treeline wraps, logs, keyholes, ditches to cross rather than going over nearby bridges, and an angle water entry with shoreline swim. Laddie did a good job, taking every obstacle and never requiring me to pick up for a slow sit.
Here are twelve pictures, two of each blind. One picture in each pair uses normal focus to give perspective on the distance, the other uses zoom focus to show details of the factors.
