Triplet,
Welcome, and glad that you found the forum. At this point, it would be hard to believe that there is a better place for A7/10 owners and enthusiasts to get information and share stories and photos (for which there is a certain lust, so we look forward to seeing that RGS). As long as I'm talking forum here, it is worth knowing that the whole effort in starting it and keeping it going is thanks to our administrator, Erling, in western Norway.
So, I think 57 puts you about in the middle of the pack around here. I'm 61 and have owned the same A10 since 1973.("Richard's 55...", on the second page of "Bikes and Pictures."
Just curious, if you care to say, whereabouts are you located? As for myself, Chicago.
Richard L.
