Note that when you approach, these spiders do not run from you. They are hunting. You are not prey. You are not important. This is serious business. Once you've spotted them, leave them to their business and find the next predator.
My brother and his family clued me into this activity. The neighbors have gotten used to them ranging through the neighborhood, checking fields and yards for the glint of not only wolf spiders, but also other nocturnal creatures hidden beneath logs and in small garden walls. The night is full of life if you know how to look for it. Happy safari ... and take only memories or photos. Leave the creatures to live out their lives and their own dramas. Enjoy.
