The forest behind our local Costco (Uijeongbu, South Korea) used to be my favorite place. It’s on the opposite side of a mountain from the National Arboretum of Korea and Gangneung UNESCO Biosphere Reserve. However, earlier this year one of the two trails was blocked off with a large sign saying the trail was now off-limits because someone was expanding their farm. I’ve also found myself feeling irritated when I walk by the pile of office garbage (desk, filing cabinet, wheeled chair) that someone dumped alongside the one trail that’s still open to the public.
Mt. Soyo further north in Dongducheon (South Korea) is also somewhere I enjoy visiting for making iNaturalist observations. Even the railing along the service road and heavily-trafficked main trail can provide some interesting sights like Siler supreus jumping spiders, cuckoo wasps, Inocellia japonica snakeflies, jumping bristletails, and spittlebugs.
