Fuel is well over $20/gallon here in NY.
I worked pretty hard last summer trying to find sources of methanol and nitro, to mix my own. Not too much success.
Certainly not success as measured in finding low-cost sources.
There is a care repair shop nearby and the owner has a top-fuel dragster, so he has both methanol and nitro.
He has offered me access to his stash.
Maybe I can trade for a plane???
