  We present a comparison of the optical and radio properties of radio sources
inside and outside the cores of rich clusters from combined samples of more
than 380 radio sources. We also examine the nature of FR I and FR II host
galaxies, and in particular, we illustrate the importance of selection effects
in propagating the misconception that FR I's and FR II's are found in hosts of
very different optical luminosity. Given the large sample size, we also discuss
the power-size (P,D) distributions as a function of optical luminosity.
