Not sure, all the banks I go too seem to act like i'm about the only one that CRH's. I have seen a few or noticed habits of a few, but if they are CRH'ers they do it on such a small scale I can't tell. I used to do 10k a week but in the last month haven't done any, and starting again soon at 4k a week again.
Any CRH'ers in Oklahoma area sound off for me so I don't tread on your areas or banks =)
