Hudkina covered pretty much anything I'd say concerning Downriver. Just wanted to add that it seems everyone down here has some sort of connection. Not sure if you'll find that in Livonia.

Hubbardfarmer, tell your relatives to check out Trentwood Farms on Goddard/Allen. It's at least a 20-30 minute ride from Grosse Ile, but it's the closest to a Trader Joe's that you'll find Downriver.
