In addition, check with the landscaping company as they would know that there is no reason for the leaves to be that wet in this current weather. There is also a good chance that these landscapers could get sick too but most likely not as there was enough water yesterday to leave a frozen pond in their driveway. No one wet leaves in 30 degree weather, as it would their job 10 times harder and unbearable in freezing weather, and if they planned on the landscapers picking it up then why would anyone turn a half hour job into a 5 hour job because that would cost them 10 times more. Logical thinking.
