Breakin’ rocks in the hot sun

As Old NFO said in comments, I’ve got a work-out goin’ on. We fought the rocks and the rocks won. 86° Fahrenheit yesterday and the hottest day of the year so-far – 16-degrees above average.
Oww-oww-oww-Ibuprofen!
We started moving the rocks off the tree roots in preparation for laying down tan-bark – something more gentle on the shrubbery. And the pseudo-curbside had rock-chip in place but the smooth river-rock (known to dirtbike riders as “baby-heads”) only wrapped around a portion of the frontage, stopping at the walkway, so we started filling-in. My little plastic wagon was taxed mightily and has not yet broken despite our efforts, the “dump” feature coming in very handy. We stopped yesterday at about 16-feet of frontage. There’s more roundy-river-rock in places we don’t need or want, but the work is heavy-lifting and we’re takin’ a break.
UPDATE: Back at it – this is morning work, by the time the sun gets way-up there’s no shade.
UPDATE-UPDATE: We’re almost to the sign-post, and other more river-rock is being removed from the driveway edging and elsewhere, the edging replaced by blocky granite hunks…
Update-Update-Update: A beautiful old Stearman in vintage Army Air Corps paint just fluttered-in to land…
