Absolutely on the stray sandbags. I haven't seen a single picture of any army camp, anywhere in the 20th century, that didn't have a bunch of random crap lying around. From my random memories of three muddy years in peacetime army a couple things that jump out are the small tents, expedient hooches, ponchos, random bits of cord and stakes everywhere, falling-apart walls of sandbags with -- inevitably -- one sandbag lying on the ground busted open and leaking sand.
