SAN FRANCISCO (CBS SF) — It can be tough to find a seat on crowded BART trains during the commute hours, which prompted one man to bring along his own.

Reddit user jiveminkey shared a photo of the man who came prepared for his commute.

Despite BART’s best efforts, high concentrations of nine bacteria strains and several types of mold have been found on train seats, including fecal and skin-borne bacteria resistant to antibiotics.

With that in mind, this guy may be on to something.
