ditto on all advice given before... also let someone know
where you'll be and
when to expect you back - so in case "something" happens we'll know where to start looking. A friend of a friend was caught up in some TERRIBLE mess earlier this year that began with an online date. Here is a link to that
article.
Partly because of this I am sure to let 2 of my friends know where I'll be if on a date. I'm on the paranoid side but i have someone call me during the evening (1) to check up on me and (2) to give me an excusde to roll out if the date is sucky.
Not saying that crazy people aren't everywhere, but please exercise extra caution when meeting people offline. Have fun and BE SAFE!
