At my local Walmart they have several parking spaces up front that have a green sign that says "Hybrid and Alternative Fuel Vehicle Parking".
Could you park your car there with a good conscience? I have no problem parking my vehicles there, as they all run on Waste Vegetable Oil. I believe that WVO is the most "Alternative" fuel that can be used. I have seen Hybrid vehicles there quite often, but more times than not, vehicles parked there do not meet the Hybrid or Alternative Fuel standard. Yes these parking spaces are not monitored in any way, but are there for use on sort of an "honor system".....Rich
