While Aaron and I were at the "wetlands" refuge last week we spotted some white pelicans in some shallow water at a nearby lake. We decided to try to get close enough to get some photos but to do so we had to walk out into the lake about 400 yards. Unfortunately this was pretty easy to do since the lake was down several feet and there was about 500 yards of lake bottom exposed. We were able to get within about 100 yards of the birds before it got so muddy we were sinking into the lake bed.
I only had the Nikon 80-200mm lens with me so my shots still look far away.
