I miss summer

Here is a pontoon. It's a formulaic poem where you compose a certain set of lines and then repeat them as you go.

Here is what I came up with --

Clouds roll heavy on the horizon
Squirrels scurry from lawn to limb to rooftop and back
Traffic pulses, congests, grinds to a halt then flows again
Coffee roars on the tongue and wakens the brain.

Squirrels scurry from lawn to limb to rooftop and back
The fair is here; summer is almost gone
Coffee roars on the tongue and wakes the brain
The dog days are coming fast.

The fair is here; summer is almost gone
August’s hazy heat awaits
The dog days are coming fast
I should never wear a watch in the summer.

Clouds roll heavy on the horizon
Traffic pulses, congests, grinds to a halt then flows again
August’s hazy heat awaits
I should never wear a watch in the summer.
