Sounds like you are going to have a great trip!
I will be working Mon - Fri from 8:00am - 5:30pm in Richmond during this time, but I can plan to go & do some in the evening at some point - I am sure my bf would love to come too - we can see if a few friends want to come with us.
I am available so far in the evenings on the Fridays, but I do have plans for both those weekends for the Saturdays & Sundays (I might be able to get out in the mornings)
There is a night cache fairly near there too - we can get some people together & do that Friday Sept 5 if you are interested? That would be fun!
You can email me at miss_sassie_lassie @ hotmail.com - my name is Becky.
