Oh dear, poor 'mato plant! I'm growing some unusual and heritage ones this year, take a look here http://www.seedfest.co.uk/
I'd really recommend the company, both for quality and range. Although probably all that will happen is we'll get so much rain again this year, like last year, that blight will rear it's ugly head and claim my tomatoes again :o( Oh well, I still have to try as it's cheaper than buying organic veggies, and far less airmiles!
The Mississippi river sounds a bit scary right now :o/ Are you in any danger of being flooded?
