Yes, taking flight training out of Gillespie (in east San Diego), you
basically head southeast to avoid all the airspace restrictions around San
Diego - but after that it is pretty easy.
I saw a mid-air collision between two Cesenas out the window of my home, as
there is near-constant air traffic of all types, sizes, and altitudes around my
home southwest of Gillespie.

The airspace is so regulated because of a mid-air collision in 1978 between a
small plane and 727.

<http://www.sdpolicemuseum.com/PSA-Flight-182.html> There haven’t been any
other airliner collisions since.
I have passed basic flight school and took some training flights 20 years ago,
I haven’t been back in the cockpit since.
It is interesting to have some of my old flight knowledge be useful when
mapping airports and their navigation aids now in OSM.
Here in Japan, there are no general-purpose airports in my region and very
little private traffic - I see mostly gliders and military helicopters when out
cycling (and airliners at cruise).
These are the airstrips round me:

winch-launched gliders (a parked winch truck pulls them airborne with a
high-speed winch, like a catapult)

tow-launched gliders.
skydiving airstrip. the plane and skydivers use the same field. The only
amenity is the nearby trees for picnicking under.
