We study the evolution of regions of space with various initial field values
for a simple theory that can support hybrid inflation. Only very narrow domains
within the range of initial field values below the Planck scale lead to the
onset of inflation. This implies a severe fine tuning for the initial
configuration that will produce inflation.
