Nice GlenGarry quote.
Browsing through both BN and Borders locally, I haven't seen HoH on the shelves much. A couple do have copies of SSHE, but not all. Which is both a bit surprising, and a shame considering the two of them are far superior to most of the crap that the local stores carry.
I haven't read TPFAP, nor do I see the need. ToP is great, but it's also enough for me.
