Place 2 cherries in the bottom of two rocks glasses. Cut 2 of the orang slices in half and put them in the glasses, then muddle with the cherries. Place a large ice cube in each glass. Skewer the remaining cherries and orange slices onto 2 picks.
Combine the simple syrup, bitters, bourbon and club soda in a shaker, cover, and gently turn upside down a couple of times to mix everything. Don't shake or the club soda will go flat!
Divide between the two glasses and garnish with the orange slices.
