We study the evolution of regions of space with various initial field valuesfor a simple theory that can support hybrid inflation. Only very narrow domainswithin the range of initial field values below the Planck scale lead to theonset of inflation. This implies a severe fine tuning for the initialconfiguration that will produce inflation.Comment: 11 pages, LaTeX, 8 figures in eps forma
