An interesting thing about DP's is that they tend to not be very
GPS-friendly. They're often full of stuff like intercepting bearings, and
determining when you've crossed a certain radial. Nothing you can't do
with a GPS, but people tend to be less familiar with these functions than
with just going direct to a waypoint.

Then again, portables like the Garmin 295 and 296 have an RMI option, which
would make flying this particular ODP very easy.
