I'm looking for a venue that can hold up to 150 people in Montgomery County (the closer to Rockville the better, but we can travel for the right place) for an evening party in March 2017. The bat mitzvah girl loves nature and the outdoors, so a place with a rustic decor and/or views of nature would be perfect. Also, if possible, I'd like to bring in my own caterer (instead of having to choose from an approved list of caterers). Any thoughts would be greatly appreciated! Thanks.
