To persevere and reschedule, good for you, BNLsMOM! You WERE brave! And you can do it again. I TOTALLY understand the driving disorientation thing (OMG and how!). Maybe next time it won't be raining, or you can take a test drive during the day to learn your way there, or someone else could drive you... a number of options there.
Meanwhile, be sure to give yourself big kudos for venturing!
