UPDATE: I figured I would tell everyone about my experience as to add to the information on this site...
Grizzly is HUGE. There are two lines of cars, one rezzie line and one back-fill line. There is no camping or trailers of any kind allowed. Arrive early and sleep in your car. It's first come first served, just like old mendota.
When it's your turn you have three options. Free roam, or select your own assigned blind in the crescent unit, or try for a random draw blind in the pond 11 unit. Most veterans who know the place go free roam. They bring bikes and it's a rat race to get to their honey hole. There is a requirement that everyone bring 12 deeks. I thought this was odd so I asked about it. Apparently there is a problem with people coming with just a gun and shells and setting up next to someones spread. Go figure.
Seems like Pond 11 offers the best blinds with quality birds. If you want to hunt pond 11, you draw a number out of a bucket. Completely random. If you don't like your pick you can toss it back and pick your own crescent unit blind or go free roam. I think there are about 25 or so blinds in the whole area so blinds are limited but it seemed like the crescent blinds were available very late into the morning as most people go free-roam.
The blinds are buried plastic barrels on a mound of mud. Zero vegetation and zero cover. Very crappy if you ask me. The blinds don't have lids either so they are filled with 5" of water.
I shot what is supposed to be the best blind in the crescent unit. In the morning we were passing on the spoons. Pretty slow but I was able to shoot a nice mallard hen (The drake got away from me. He should be dead though), 2 GW teal, and then things got really slow so I shot a spoonie. On a side note the spoonie had rice breast so I chucked it.
Oh yeah, the place is loaded with Elk too!
