Welcome to the forums Gunn, got a great group of fellas here who are all to willing to help. I'm a bit of a newbie to Turkey hunting as well, so i can give you some advice and perspective from that standpoint and let the pros and verterans here discuss the finer points. As for where to start, half of the battle is locating them and since your two hours away from your property its probably unlikely you get an opportunity to roost the birds the night before. Having said that i think you overlooked a very important piece of intel you can use to help locate them sooner...the farmer! If he's actively farming that land he'll know where the turkeys are, so just ask him where he's seen them recently and at what time of the day. If he's seen them in an area within the first hour or two of sunrise and sunset, its a good bet their roosting near by then its just a matter of putting your self within 100-200 yards of that area and wait for flydown. If the farmer does not offer you any intel, all is not lost..but since your bowhunting from a blind its going to make things a little harder. To make it easier on yourself, grab a topo of the area and find the highest point on the property and if there is water running nearby so much the better. From that highest vantage point use your locator call about a half hour to 45 min before sunrise...really when first light is just breaking. Give a few hoots on the Owl call and listen. if you get a response, don't call again...just try to close the distance from where you thought you heard it...setup camp...and wait for flydown. If you don't get a response, get back in your truck (or walk) another 1/4 to half mile and hit the locator call again. Once its sun-up put the Owl call away and just use the crow call. keep moving around the property until you get a response...and if its farm land I'm assuming there are two tracks all over the place you can drive from one field to the other? This will be key for you since your lugging in a bow and blind and will help you quickly survey the property and hopefully get setup on a bird quickly.
As for the calling...here is where most make their mistake (myself included). best thing I can tell you is keep it simple and less is more. Stick to the 3 calls, but really all you need is to be able to cluck and purr. Some soft yelping can help, but only if nothing else is working. Once they fly down or its sunrise a few soft clucks, some purring, and ground scratching goes a long way. Only need to do it about once every hour..and only if your not getting a response. Trust me they will hear your calls.
I'll let the other fellas chime in here...they are infinitely wiser than me when it comes to this subject.
Good Luck and keep us posted on how it goes!
