I'm sad to see them go. Love em or hate em, they provided some great content at times and I think overall contributed a great deal to the pipe community.
I wish both of them the best and I especially wish Jon David and The Country Squire continued success at the shop. It can't be easy running a successful B&M Pipe Shop in Jackson, MS. As a Mississippi native, I can tell you that there are not a whole lot of pipesmokers to be had in that market, but he seems to have done pretty well (I'm sure the online sales don't hurt).
I think our hobby can use all the exposure it can get considering the current overall attitude regarding smoking of any kind. So CSR leaving the airwaves certainly leaves a void in the market. Hopefully there is someone else that can fill that vacuum that will appeal to CSR listeners. I personally liked their format (if a little rambling at times) and the different series of shows that they put out there.
I wish them well.
