One reason I had picked the Arboretum for this task was the lack of any cars. Well, except for the occasional maintenance vehicle. I ended up walking right into this parked truck, having to feel my way around it, and then get out of the way when it wanted to drive past. I tried to get a picture of the truck that had caused me so much trouble, but did a poor job of centering it in the frame since it wasn't making any noise and I had to rely on my memory of where it might be. This was barely forty feet from where I had started, but I was already entirely lost. I tried to find my way by following the paved surfaces, but kept getting caught up in little cul-de-sacs (the area around that water fountain might have been one, although I don't remember bumping into the water fountain itself) and getting turned around. It was around this time that a couple of kind passersby noticed me having some trouble, and asked if I was trying to locate the bathroom, or anything else. I asked them to point me toward the California natives section (my favorite place to walk and the general goal I had set for myself at the outset), and as they were going that way, they invited me to follow their voices.
