T,try to find somebody else to go with you. I wouldn't go alone. Think of some other friends I am sure you have, I can't get there fast enough.
I think todays email was the best you have had so far. Not because of the context of course. He didn't have to do it, shows the communication lines are open, and proves you did a good job making him feel comfortable to contact you. WAY TO GO!!!!! I think Essie gave you some great advice regarding hints etc. Be careful not to show you are extremely eager. Just that you are willing if circumstances allow it.
