Hi Rob
Ahh, truly you are an educated man!! You've information vegetable, animal, and mineral.
If you're in Wpg end Feb, I'm there for the last four days of the month on a short course. Checking with my betters if I have auth to rent a car, then plan to haunt around a city I once lived in but I have not been to in about 25 years!!
I need to bring "Off", right?
regards
Darrell
