Proposition 68 would allow California to sell $4.1 billion in bonds to pay for desperately needed improvements in parks and water systems. It’s a sound investment. Failing to upgrade our infrastructure now would likely mean higher costs in the future. The bond sale would, of course, require interest payments over the years, but they would appear to be well within the guidelines for prudent financing. Californians should vote yes. There are a lot of good things in this bond.
