Thanks man. Unfortunately the handlebar wasn't the only thing that rusted off or otherwise broke. RIP the bike I used when I was a younger and more hopeful person.
You have to abuse a bike pretty damn badly for it to truly be unsalvageable. Either you're too lazy to fix a fixable bike or you were so lazy you neglected the poor thing to death, so either way, that's on you.
That salt breeze is no joke, it takes a constant active effort to prevent it's destruction.
The next bike you get be sure to take good care of it. Seal it with marine grade polyurethane where you can and keep the parts you can't well oiled and clean of debris.
