i'd just say do a lunch date or something in the afternoon, so in case it does go a lil rocky, you can always bust in with, "wow....it's getting late and i have this...
thing i gotta get to....", and it would be at an hour that's feasible for you to actually have something else to do. ya know? you may wanna check out a dating story on TLC for good ideas, too...those dates are often afternooners and don't seem to last that long. i know, i know....a guy watching a dating story, but hey....trying to help here!
you may think a picnic is a bit too cozy for date #2, but it would probably take up a decent amount of time and a good way to get conversation flowing....providing weather is nice. coffee places, bowling allies....traditional places but kinda not, those are fun, too. but def. something early in the day so if it goes bad, you can quit it with a good line, or you can carry it on if it goes well.
GOOD LUCK!
