Go to Dodge City, then go to the lower part of the bridge. Follow the path on the other side to reach a beach cave. Look inside for a life power-up which will reappear over time after you leave the area. Note: The cave also contains ammunition and money.

Go to Hecht Ranch, then go to the shack next to the windmill. There you will find three whiskey bottles which will reappear over time after you leave the area.
