Switching Circuit
A buried wire between house and garage has only 3 conductors. How do you
utilize them to provide both constant power from house to garage, and 3-way
switching for lights in the garage at either house or garage?
I used two 3-way switches and a relay.

You are right. I don't need a relay. Simplicity at its finest.

You could do it with just two SPDT switches:
|
A O----O------O--Cable--O------------O-----O A
\ |
SW1 O----O--Cable--O--(Bulb)--O SW2
| \
N O----O------O--Cable--O------------O-----O N
|
House | Garage
Easy!
