B)Jim Walker the NMA Traffic Safety Consultant was AGAIN on WILK here:
It is about 36m and focuses on red-light cameras, proper speed limit posting, lane courtesy, etc. He goes back-and-forth with LA Tarone(the host) and takes listener calls. Can listen in Flash or download as MP3.
If the above link fails, go to the WILK site and do a search for Jim Walker and the two different interviews pop up. WILK is near Wilkes-Barre, PA, but this info can be helpful anywhere.
Very good stuff.
