Good idea, Sue. I thought I'd done well to get almost 100% success rate with my 3yr old tomato seeds (open packets, not kept in fridge). Expecting a low germination rate, I planted extra and now have a tomato forest out back. The germination of your 20yr old seeds is quite stunning. I don't drive but, health permitting, I'd be up for sharing petrol costs to visit gardens, also for meeting up to talk about our own, swap seedlings etc ;-) Mine needs a complete overhaul but for the moment it's working quite well as a wildlife garden which I'm really pleased about as when I moved in there was no garden action at all.
