I think the easiest call to use is a push button call. They don't sound the best but will do the job and are very easy to use. BTW electronic calls are illegal in Mo. I would only use a blind if I was bowhunting, taking kids, or had some kind of condition that you can't sit still. Just put on some camo and try to find a nice big tree to setup on. The wider the better.
I don't have any ideas on hunting locations around Lee's Summit, but you could go to
www.mdc.mo.gov and find a place. I would start looking now and try to find a place that might not have very good access or is a pretty good walk. If it is easy to get to, you will probably have company on public ground.
The most important part of being a successful turkey hunter isn't your calling. It is your woodmanship and knowing where the turkeys want to go. If you get where they want to go and sound remotely like a turkey you can bag one.
Don't get caught up on what is hot or something you see on some video. I have found that these things are designed to catch hunters not turkeys. You might try to buy a cd or tape of real turkeys and listen, listen, listen. You'll find out by hunting that turkeys don't call as much as you might think they do.
Equipment that I think are essentials to good turkey hunting would be camo, crow call (daytime locator), owl hooter (early morning locator), call, shotgun, and shells. Keep it simple and remember that time in the woods scouting will be the most valuable thing you can do to assure your success.
