When to rips get propane at 7:30 and that kid working in the store told me that he could fill my take after dark because it was a safety issue. My Boyfriend works on a production rig day and night for the last 40 years and I know for a fact that it being dark out side has nothing to do with safety or filling my propane tank. FYI the sales of propane winner increase in the winter and it get dark a 5:30.
