It's a pity you won't be around the Northwest in late October. The town where we live, Anacortes, has a big biker event called the Oyster Run the last weekend of the month. In the 16 years we've lived here, the biggest crowd was about 30,000 bikes, many wth two up. The weather is unpredictable at that time of year (a lot like the UK) , so it can vary a lot. I always go into town to look at the bikes and it's VERY rare to see any Nortons or AJS and not many British "classics" either.
It will be interesting to see if any 961s show up this year.
