With gas prices the way they are, im tempted to build a trailer for my Stearman, to pull behind my VW trike. My flatbed is costing me about $5.00 a nite to go flying. Thats about $30.00 a week. I figure the plane uses maybe $2.00 a night. Stll not too bad, and it's alot cheaper than my old hobby (drinking beer). Gave that up in 2002 when I started flying.
