Fred--Piers has been around since the 90's---my memory doesn't recall specific dates, but he worked for BD back then and then opened up what is now PDR in the late 90's or early 00's---he's a stand up guy and well liked, so since it seems you don't know who he is and what he's done I'll forgive your oversight(bet that puts you at ease, like you were all tensed up anyway over this)---really though we all think that everyone knows of Piers, PDR, etc... . and I thought it odd that such would be brought up---he sold these hitch covers at TDR events and I'm pretty sure he did the logo with the TDR's blessing and since it's been around for so long it just came across that you were trying to stir something up---there are others that can give more exact dates, but whether they decide to or not is up to them, but my dates are fairly close even if vague---
on another note---thanks for your service to our country-----chris
