If you would like to write him, and he will respond likewise, you will need to use the snail mail system. You can always address your letters and packages to the mission office and they will then forward all his communication to wherever he is serving within the mission.
Elder Thomas E. Blair
“No unhallowed hand can stop the work from progressing; persecutions may rage, mobs may combine, armies may assemble, calumny may defame, *[and hurricanes may hit - Houston is in IKE's pathway,] but the truth of God will go forth boldly, nobly and independent, till it has penetrated every continent; visited every clime, swept every country and sounded in every ear; till the purposes of God shall be accomplished, and the great Jehovah shall say the work is done.”
Prophet Joseph Smith
From the Wentworth Letters, March 1, 1842
*While talking with Tom this morning I mentioned the possible disaster looming toward Texas with Hurricane IKE (it could just end up being a heavy storm of sorts, but you never know). Anyway, not that Tom is all about disasters and injury to people, but with no fear he replied, "We're all about it, because missionaries are all about service." Tom was one of 11 missionaries gathered at the airport this morning heading for the Texas Houston South Mission ready to serve no matter what. I'm so pleased and inspired by their devotion.
