I was planing on doing that very thing---a cook out at a state park, however, the weather is not going to cooperate (extreme thunder storms with high winds are expected).  Normally we just call everyone and let them know, but I was wondering how to word it in an email.  Would something like the following be OK:   "As you know, Jennifer is moving to Tennessee on August 26th.  If you'd like to bid her farewell, please stop by TIMBERS Restaurant.  Jennifer will be there from 6:00 until 8:00.  I've included a menu for your convenience."
