First off, don't give up on a spot after just one or two sits. Them hunting shows are highly edited and give everyone the misconception of this game being "easy". If it were easy it wouldn't be fun.
Second, if space is an issue in the blind (you may have tried this already), get swivel chairs with backs for comfort, but no arms on them. This will save a ton of space and save on your back. If your butt hurts, use a hot seat or cushion seat that can just attach to your belt loop. Those swivel seats are very important so you can swing your legs out of the way and set up your body in the right position to shoot sitting down. Also, put yourself in the back corner of the blind if possible. This will give you room to move your bow around to where you need it.
Third, if you can't sit in the back corner, majke sure your partner is. Get him out of the way as much as possible.
Fourth, if there is any place in the area you want to hunt that is slightly elevated, like a little pitcher's mound type place, get on it. It'll get you up a little higher and increase your visibility some.
Fifth, be comfortable! Nothing worse than sitting there miserable because your seat is on uneven gorund or, in my case, my back starts killing me.
Sixth, if you're using a compound, get yourself a ground bow holder or use a hook on one of the poles above your head to hang the bow on and get it out of the way.
Seventh, be patient and have fun! Being outside and enjoying the wildlife is what it's all about. Remember, hunting isn't always about the kill.
Really appreciate you taking the time to give me so much advice!!
