As a former owner, +1 on Vince's comment about straightline only. Also quite expensive for the 1700 and pretty limited fuel & comfort range. The new Honda F6B got very positive reviews for comfort and handling in MCN if you need to have a luxo-barge. The K1200LT might be a good alternative if you are looking older/used.

Earlier this year I went riding with my friend John who lives in north San Diego county. He had just received a 696 monster from his wife for his 78th birthday. He still has 5 bikes in the garage, goes all over the western US and rides offroad with his (adult) kids & grandkids regularly. He's still very smooth in the twisties and can still do the long days (although he has switched to the cruisers for the long stuff). He has no special regimen other than walking a lot with his dogs. Like Gramps I will ride until I can't, and it's nice to know that there is something like the Spyder out there if i get to the point where that is the best option. 

Before we go too far down the road on fast food bashing I'd like to point out a couple of upsides to eating at McD or wherever that may not have been considered:

1) Fairly accurate nutrional information. Any successful dieter will tell you that tracking what you are consuming is job one.
2) Portion Control. 

Seriously, you can eat <reasonably> healthy at McD. The grilled chicken is pretty good from a caloric & fat standpoint and the fish sandwich is OK if you custom it without the big dollop of tartar sauce. All the major fast food chains have now gone to trans-fat free cooking oils so fries are less of a no-no than they were in the past. 

It's the beard.

My max is 42k in 1983...but I lived in CA and had no other wheels. 100k is indeed mind-boggling.

Ray - I've ridden to/from Miller WSB 3 of the last 4 years and I think your chances might be better than they appear. I did not go this year, but the 2009 race was also late May. That trip included a two-day loop on the front side through higher elevations in CO & UT and the only road that was iffy was Rocky Mtn Nat'l Park, which had been open for less than 48 hours prior to my arrival. They do a pretty good job keeping the roads open and clear, since many of them are the only access to tourist/resort areas. Based on experience; you just need to have a contingency plan, and be prepared to stop and/or backtrack if the weather gets crappy. DAMHIK 

I do this with trepidation, but if Lloyd's brave enough then I guess I should be.
A staged pic for my friends in CA, taken on lunch break in December 1988. That was the bike collection at the time:
