SOLUTION to the last puzzle

Summer's here! Here's a themeless that hopefully feels like drinking freshly-squeezed lemonade on the porch at night, with fireflies in the air and a bonfire in the distance. You can hear the porch lights buzzing gently, but that doesn't drown out "Country Roads" playing from inside. You take another sip of lemonade (it took ages to get the sugar/lemon balance right, but once you got it right you knew you might never make a batch of lemonade like this again, so drink up while you can) and watch the smoke as it drifts into the sky. You know, that feeling.
