We have friends that are in their 80s still doing it!!!! And as I think, I realize I have 3 sets of friends in their 80s still traveling. Do what's best for YOU! If you can still hook up and drive SAFELY, then go for it. As for drivers that cause problems on the road -- usually they say "OLD drivers", I have taken a tally for the last 6 months. We've had or seen near accidents while on the road.....a total of 12......and only 1 was "caused" by an "old" person. The young people are LOONY when it comes to passing, etc.
