If the creek runs into the woods from the field, then use it as a funnel to get the birds into your decoys... make sure that you are set-up on the side the birds are roosted on, get in place well before light... use soft tree yelps once legal light arrives. When you have a tom gobbling pay attention to how he responds to your calling. When the tom gobbles, hit him with an aggressive yelp sequence... if he gobbles back before you are done, keep hitting him with aggressive calling to keep him coming... if the tom gets timid or doesn't call back for a few seconds... then slow down and soften your calling... only call to get him moving toward you again, and use more clucks and purrs. Make sure that you pattern your gun with the loads you will be using, pay attention to POI and if the patterns have holes... if they do, then try other loads and/or chokes. The tightest chokes don't always deliver the best (even) patterns... I would recommend #6's, as pattern density is more important than pellet energy in anchoring toms. Good luck.
