JTBok: See previous logs by Dr.Evil! - the GR portion where the CC was mangles apparently by a car crash.
I removed the damaged CC and did not replace or move it. Why? - The other end of the GR was covered with vines, weeds, briars, dirt, etc.; I considered placing a new CC in one of the nearby trees, but there was too much trash to make it enjoyable. I'll keep an eye on this in case they replace the GR, but the third reason I'm not crazy about GR caches (danger from passing cars), is also a factor here.
