Give me a tax measure that specifically says how it will be spent, the % that will be allocated to each item the tax is funding and lock that funding down so it can’t be misappropriated, I will vote for it. 
I am disappointed that the Springfield gas tax did not pass. It is a good way to capture additional dollars from people passing through town on I-5 or heading up the McKenzie.  I think most people in Springfield buy their gas in Eugen at Costco.
