Ferris Swap? Ennis/Kaufman/Garland/Mesquite People?
Ferris, Texas (just off 75, which is also I-45, which is also the Houston Highway) has a very nice park with a pavillion & a barbeque pit...
& it's free free free!
It's right next to the library (bathroom!), which is open from 10 AM til 2 PM on Saturdays.
This site might be perfect for gardeners who can't get to the FW Swap.
Let me know if you are interested!
