Whether you are hunting a blind, pit, layout, or just plain laying in the field amongst the decoys ... as the season progresses, and the birds get seasoned, you must conceal yourself. I share the following picture:

If in the above picture, the doors were closed on these blinds, and my brother wasn''''''''t sitting there texting, you wouldn''''''''t even know we where there. So many hunters spend so much time setting up the decoys and then spend the last fleeting minutes before the first flight trying to camo their blinds.
Concealment should be one of your priorities. You can purchase artificial grasses ect, to help camo your blinds, but nothing beats the natural vegitation that surrounds your set up. I am a firm believer in the later. Add a couple of tools to your equipment list for your next outing. A fan rake, hand pruners, saw and even a shovel. A little extra work on your part up front will pay great dividends on your success rate.

"Enjoy the Pursuit!"
