I have some ideas. No Toll Roads.
Stop spending highway money on bike paths, mass transit, parks, greenbelts, diverted to the general fund and other non-road activities. Then, get back to me about any shortfall.
If it is truly a real shortfall and not a fake one, I’d be willing to see an increase in the gas tax, but you have to prove to me the money you are now getting is not being wasted first.
