Hi Ted,
I'll always try to plan a VFR route for true bush flying, but if I encounter IMC, I want to be sure I can continue IFR.
So, my approach is roughly as follows:
create a low level route with FSC.
Study the charts and maps around this proposed route.
Lay out a VFR route that follows terrain and or man-made features (follow valleys, highways, rivers, etc.)
Identify visual reference points every 5 to 10 minutes of the route
Determine the minimum safe altitude for each segment, including the IFR route
punch in the IFR route in the GPS (load the flightplan as you saved it in FSC

)
Estimate or calculate the fuel needed
Fly the leg, and look around a lot. Absorb the environment. Enjoy!
That way, should you encounter weather that does not allow for VFR flight, you can always climb to the minimum safe level, and proceed to your next IFR waypoint.
All this planning takes a bit of time, but I find that it makes for a good part of the flying fun, this planning bit. Especially if it all works out as you planned

Have safe flights!
Go WILD

PS. Yes, the approach over the river from the east is always good for an adrenalin rush. Low and slow approach, with a steep, descending turn on short final. Phew!
