Do be careful, I cut my sole running around barefoot.

I was in dance heels here, and usually wear some variety of shoe mostly Ballet slippers. Keeps my feet clear from pokies and sharp things.

Yeah, the sharp bits are my main concern when looking for mud. Especially considering former or current construction sites likely have nails now.

Ooh, I did play at a construction site once, They were just doing the initial excavations (construction mud) and there were no nails or other things to get in the way. they dug up some dirt, put it in a big pile, then a few days of rain totally saturated that pile and it kinda started to turn to ooze. It was amazing, nothing but the dirt and some rocks, and pure muddy muckky ooze. This was at the onset of my muddy time out. I did this in white school tights and a camisole undershirt and nothing else. I didn't want to get my school clothes mucky so I did it in my underwear more or less, sans my panties.

I tucked my camisole shirt into my tights and climbed up the oozing mountain of muck and my feet kept plunging into the slope until I was wallowing in it up to my hips I got soooo muddy and outright ruined my underwear with all that mud I played in it for what seemed like a few hours and got so dirty. Took forever to clean up down in a stream at the below the construction site, and went home in the rest of my school clothing having ditched the cami and tights. (they were unsalvagable)

I saved my school clothing from getting dirty, and everything was fine!!!

That sounds like the best time ever.
