Tin-Man,
I had my standrd SPF now for 7 years, (changed to firefly) as said already you will be heard before you are even seen. I live in a very quiet area and to respect the others i keep the RPM low and short gears until im further out.
Coming home at 3am is a no no...
But just do it, but keep the RPM's down.
Happy cruising
Skip.
