A 'plog' is a jog where the jogger picks up litter.
Plogging socials occur 5:30pm every Thursday. The first and third Thursdays of the month occur at Semaphore (meet outside Copenhagen), the other Thursdays occur in various locations. Check the Facebook page for the week's location, show up with a bag, and plog! Post-plog coffee runs often occur.
The first and third Thursday of every month involves a plog at Semphore - with all ploggers offered a post-plog deal at Copenhagen of a $2.50 hot drink OR a free second scoop of ice cream.
