Creek bottoms can be great locations with the right set up. If you can find a "terrain corner" or inside corner or field edge or other feature near that creek bottom they are great to access for evening or even sometimes morning hunts in hill country. I walk up the creek if evening thermal flow has begun down or if I'm not sure if it has switched yet, I "side hill" it with the wind quartering from my side making sure its blowing away from the suspected deer bedding area. I don't worry about the thermals as I side hill in because the creek bottom and terrain feature I'm setting up will still be far enough to the right or left of me to not catch my scent on the still rising thermals. I make sure the creek bottom and terrain feature are to the right or left of the majority of the bedding area. They are bedded above trying to catch rising thermal scent so with this set up your moving in just far enough where the prevailing wind will blow your "entry scent" away from the bedding area. I set up at that intersection of the creek bottom where a terrain feature "closes in" on the creek bottom. I then rely on a bit higher saddle setup to make sure if there are still rising thermals that hopefully my scent will drift above the bedded deer as the younger ones begin to move toward evening feeding. The best thing about this though is as thermal shift begins in the evening, the creek bottom acts like not only a water shoot but also a "thermal shoot" drawing thermals and your scent down and away from where you suspect most of those bedded deer going out to feed to filter through. I've sent out milk week on a SW wind on this set up and it will start t o drift up the hill and then as it gets to the creek bottom it shoots down the creek. These are great if you can find one and can be nice quick setups close to roads or parking areas for evening hunts.
