Throw the peach slices and mint into the tall glass with the whiskey. Use one shot for a single, or two shots for a double. Muddle it all together well so that the peach and mint flavors get into the whiskey.
Fill the glass to the top with ice.
Fill the glass to the top with ginger ale. A good gingery micro-brewed ginger ale would work really well here.
Sip and relax, and do chew on a mint leaf or peach slice here and there.
