As well as bring near a convention center, shops, food, and good views, public transit.

Alas, you've filled in some of the blanks and given her some food for thought.  

I am researching Food Truck Parks, I have searched the forums and have not found much information on them.

The owner says it’s a good opportunity for food truck rentals.

The D.C. area is so transient really anywhere should work, the military also pays an insane per diem on mtr, I had a friend who was on assignment and rented a 2bd condo in navy yard for like $7500 a month (I was paying $2700 for a long term for context) they also unrelatedly gave him like a $100 food budget or something per day, this dude ate at every michelin star restaurant in the city lol.

We also provide 2 refrigerators in the home as we tend to have 4 bedroom homes and want everyone to have their own personal space for their food.

Development, low unemployment, growing population, one of the largest universities in the country, housing demand, central hub within a 6-hour drive of at least 6 other major metropolitan areas, and last but not least, great food options! 

In your septic system, they either get hung up in your pipes, hang on to the tank baffle, or if they make it past the baffle (or worse, if you have no baffle) get hung up in your drain field pipes.Without trying to get disgusting, I would have my guests use fast food napkins, a washcloth or their hand before I'd let them use flushable wipes. 

Despite the downsides that have already been mentioned, I haven’t been to many towns in the US that have nearly as much character/beauty/friendliness/incredible food/outdoor activities/etc.Good luck with the search and feel free to DM any questions!
