I just read this thread, and want to add my condolences. There's few things worse than a bad accident on anything, much less a bike.
One thing I learned the hard way is that I encourage people to follow their gut feeling when it comes to riding. If they feel like they should quit riding, I don't try to change their mind.
Years ago I encouraged my wife to ride my dad's motorcycle at his lake cabin. She said she wasn't comfortable with it, but I kept pushing for her to take it for a spin. She was gone about 10 minutes when a friend drove up and carried her out of his truck. She had a deep gash that went clear around one knee. I borrowed my dad's Jeep and rushed her to the hospital doin' about 90. The hospital was 50 miles away. The wound was so bad that they kept cleaning it and picking gravel out of it and left it open for abut three days. She almost lost a leg. She now has a scar almost an inch wide around 2/3rds of her right knee. She was in a cast for about 6 weeks. As time goes by she's having more trouble with it.
About another 7 years later, in 1987 she decided to take the Rider Course and get her license because she wanted to be able to pilot my dresser in case I got sick or hurt while on one of our annual long bike trips. I though that was OK.
By the following year she wanted to get her own bike. I tried everything to talk her out of it because I didn't want to feel responsible for another accident. When I knew it was HER decision to get it, we bought her her first Harley. Since then she's taken the advanced course and has ridden her own bike on some of the long trips.
I know this is long winded, but whether to ride or keep riding is an important decision that should be made after serious soul searching. -No doubt it's a risky sport. -Steve
