I'm a brand new Knottie... got engaged last Tuesday.
Very quickly, my finance and I have gone from the idea of a church wedding/reception with bells, whistles, etc. to the bare minimum -- what's really important to us is to be married, not to have a production. (NOTHING against anyone else's plans; it just was seeming too complicated for our situation.)
So, we are thinking about having the ceremony in the Public Garden in May 2014.  It's only $100 ($50 if you live in the city), plus $50 for the license.  We'd still be married by my priest (I hope), but we wouldn't have to spend $2600 on the church, plus the reception, plus plus plus.
Feedback?  Thanks in advance.
