LOL! Well I reckon you're going to have 4 sit-spots - river, wood, field and footpath
If I were you I'd just take a plastic bag to sit on and make sure you have your waterproofs and something to eat and drink in a ruck-sack and just wait. I'm sure you're natural instinct will lead you to a suitable spot - just use your ears and eyes and you'll hone in on a perfect place to stop for a while
Good luck and I hope you get to see many a species on your day out tomorrow!
