Carry a plastic jacket, baby wipes, and a can of under arm deodorant spray with you. Place your plastic jacket over your shoulders, unbutton and remove your wet shirt. Take your baby wipes and thoroughly wipe, vigorously. Lastly, hit your under arms with the spray and zip up your jacket.

That should hold you until you get home.

Oh yeah!...You might wanna carry a zip lock bag for your solied and sweaty shirt
