_Everywhere_, most likely, but starting at the least-expected point.

I'm at work, and the rig is at home right now -- with both antenna feeds 
disconnected from the tuner _and_ with power disconnected from TX and RX.
The only remaining connection is to ground, and that does still present a
potential[1] vulnerability.

Any time T-storms are predicted in the area, the antenna feeds get pulled
loose, as does power, before I go to work. While it's a real pain to avoid
cross-threading the @#$%^&*( PL-259 sleeves when I put stuff back together,
it beats forking over bunches of bux for a new transmitter and/or receiver.

[1]		No pun intended, I assure you.
