Hey jjj,
Wish you luck with your worm project. Tell 'em to go forth and multiply.
I mulch my garden quite heavily, and have done so for years. Now, when I turn the soil over. Every forkfull has dozens of worms in it. Big, fat long juicy ones.
So, when I get to that stage when 'no body likes me and every body hates me', I can surely go to the garden and look at the worms.

I ain't eatin' them snakes.
Cheers Marty
