When running a USPS route on a rainy day, don't push too hard for speed.
When running a route on a rainy day, I basically don't compare my time to sunny days anymore. Especially with wooden steps, porches, or mossy edges on driveways—if you're in a rush, it's easy to slip, and if you fall, the whole rest of the route is a waste. I don't grab too much DPS in my hand at once; it gets sticky when the rain hits it, and it's even more annoying if the order gets messed up…
