Earthworms

We've had some heavy rain these past few weeks. I noticed on the walkways a lot of earthworms days afterwards. I've always seen earthworms, but recently (these past few months), I've found that they are overabundant on the pavement after rainfall. I'm talking like 50 or so in a small area.

This made me do some research last weekend. I wanted to know why there were so many. There are 2 theories.

• Ground has become too acidic.
• Ground is too saturated and they need to come up for air.

Which ever theory, it is a shame to see so many of them die. Today, I was running along the river when I came to a long downhill where there were so many of them just lying there. I quickly tip toed thru them hoping not to harm any of them.
