Although objects within close vicinity of a coil may affect the coupling and
resonant frequency of the secondary etc..., your objects are far enough away
so that the effects
are probably negligible.  Plus, even if they did affect the coil, as long as
the coil is tuned correctly it should work fine.

I'd be much more concerned about running the coil near the 500 gallon
propane tank.  Thats darn right scary.
