Where I hunt in Utah, we tend to spot and stalk in the mornings, and if it's dry, set up on water in ground blinds in the evenings. Unless its very dry and you have pattered the deer well, spot and stalk hunting in the evenings is ususally more productive. You need good optics, patience, a good sense of when a deer is stalkable, and the ability to sneak. Sometimes it pays to wait and stalk the deer after they've bedded. At other times, it pays to go after them while they are moving and intercept them. For spot and stalk bow hunting, patience is the key. It may take 10-15 stalks to have everying fall in place. However, once you've pulled it off, you are on cloud 9! Most evenings, I'd rather blow a stock than hope a deer comes to water. However, if its dry and you've done your homework, sitting on water is a better bet. Good luck.
