Lou have you thought of the type of bikes that they are getting around here on. Have a two stroke motor sits in the middle of the bike and runs on a oily rag. At the moment the prices have just gone up about five cents a litre here to $1.45 in Newcastle NSW. There are also electric bikes getting around here as well as the electric buggy's that the olds are using.
That's the way the mop flops.
My thanks to Brian for this site.
