I can't believe I did this, but my grandma just called and told me that I did not include the street address of the venue on the invitation!
I suppose there's nothing I can do now. The addess is on the website and I do have the name and city on the invite, so I suppose everyone except for maybe a few older people will easily be able to get the address.
just a vent unless anyone has any suggestions for a fix for this issue.
