What are the huge thick brown spiders that make webs across the trails in the Pines (mostly seen in Wharton) on hot nights? the webs are ultra thick and they usually go across trails up to 20 feet across. The spider it'self seems to stay in the middle and is pretty large in diameter and is fat. I never see them during the day, only at night. It seems whenever I go for a night ride I end up with at least on of these crawling up my windsheild. What kind of spider are they, and can they harm you? I have heard that they are recluses (spelling?). I have heard wolf (I don't believe), and I have heard just plain old "pine spiders".
