Who's Got Game? How should I play this dame?

So I had a pretty decent blind date. Didn't expect much and I would say we ended up hitting it off. Nothing romantic obviously bc it was a first blind date, but went relatively well. Then went off on a business trip. Exchanged a couple emails. The girl claims not to check her email often so traffic is really slow. I haven't gotten a response to my volley for like 5 days. In her email back to me, there certainly did seem some reciprocity--she closed her email talk to you soon and had questions so i imagine there is some curiousity on her part. So here's my question. How do I read thru the lines here--I want to score a second date--I got thru her town in transit back home in a week. Should I just drop a line asking for a date when I get there even if I don't get an email response. If I get no email response does that mean that there is no interest? Basically, I like this chick and want to get that second date so I can hammer it home.
