The problem in agriculture in Florida is, every year we have 15,000 to 20,000 new workers who enter and all those new workers are undocumented from Mexico and Central America.
Every time we do have a freeze or disaster it exposes the reality that agriculture is dependent on workers who basically don't have a social safety net to help them. That is one of the many reasons why I think immigration reform is so essential.
