Query: Photoproduction of Hybrid Mesons   In this contribution I discuss prospects for photoproducing hybrid mesons at
CEBAF, based on recent model results and experimental indications of possible
hybrids. One excellent opportunity appears to be a search for the I=1, JPC=2+-,
neutral "(b2)o" hybrid in (a2 pi)o through diffractive photoproduction. Other
notable possibilities accessible through pi+ or pio exchange photoproduction
are I=1, JPC=1-+, charged "pi1+" in f1 pi+, (b1 pi)+ and (rho pi)+; piJ(1770)+
in f2 pi+ and (b1 pi)+; pi(1800)+ in f0 pi+, f2 pi+, omega rho+ and (rho pi)+;
a1 in f1 pi+ and f2 pi+; and omega in (rho pi)o, omega eta and (K1 K)o.
