My understanding from MEMA, is that only 20 requests for outside aid have been sent from the State of Texas EMA. All of which have been covered. As a certified emergency manger, I caution anyone from self deploying. I realize and applaud the eagerness to help, but without coordination, helpers can quickly become hindrances. I can remember from my time on the coast, we had to handle the people that got around the roadblocks and such, trying to help. Unfortunately they became hindrances, as we had no additional fuel to provide them with, and we had to feed the majority of them; taking our already thin supply line and adding more pressure. Again I don't fault anyone from wanting to help, its a great quality; but please understand the consequences.
