CW2274:
The anny was at 20' for the first 9 months after the system was installed. I lowered it at that time so that I can clean it every day during spider season. I decided that I would prefer a less accurate reading rather than no reading. The trees in the background are 30-50 feet away from the station but many are 100+ feet in height. The spiders do not climb up to the station, but they fly down from the trees using a trail of spider web as a rudder. Sometimes when the fog is the right thickness, you can see the web trailing back up to a tree.

I am not sure how much good GEICO™ gecko would do for me. There is a rock garden on the ground between the bottom of the 4X4 and the tree line in the background of the photo. It has population of both eastern fence lizards and 5 lined skinks. They are both supposed to prey on spiders but based upon the size of the lizards, there is plenty of food there without having to work real hard to get plenty to eat. The lizards did disappear for 2 summers while a black snake frequented the area.
