I may be available on Sunday the 15th, but the weather does not look promising for the weekend - the remnants of Ida seem to be stalled out just off of Maryland.
If it is VMC, I can fly the KTTA leg, preferring to transfer at 2W6, Saint Mary's County Regional Airport in Leonardtown, MD. 2W6 is outside the DC-SFRA and has plenty of transient parking and grassy areas.
Let me know if I can help.
My range is about a 250 mile radius around Houston, Texas. Roughly that would include any field within an arc from Houma, LA (KHUM) to Monroe, LA (KMLU) to Paris, TX (KPRX) to Brady, TX (KBBD) to Carrizo Springs, TX (KCZT) to Brownsville, TX (KBRO).
