In a previous article, "150flivver" said:
If all you do is fly in the local area, not regularly updating the
database is probably no big deal. If you go cross country however,
you'd be unpleasantly surprised by the number of identifiers that
change over time. With TFRs and such, it could get you into a nasty
situation.

Not a big deal if you always check your flight plan against current charts
and NOTAMs.
