  We propose yet another solution to the initial condition problem of inflation
associated with homogeneity beyond the horizon at the onset of inflation, in
cases where inflation is preceded by a radiation era. One may argue that
causality will allow for smoothness over the causal horizon scale $H^{-1}$, but
for thermal inflationary scenarios, the background inflaton field will only be
correlated over the thermal correlation length $\zeta\sim T^{-1}$ which is much
smaller than $H^{-1}$. We argue, with examples, that if the number of
relativistic degrees of freedom in the pre-inflationary era is very large
$(>10^4)$ then the thermal correlation length can be of the order of the causal
horizon size alleviating the initial conditions problem of inflation.
