Well it may take you a day or two to adjust to the humidity, but early May is usually a pretty good time around here. July through September...well good luck and God bless.
What to do? Todd Mission looks to be about an hour give or take from the center of the fourth largest city in the country. It is all there depending on your tastes. I don't really think of Houston as a tourist destination as we don't have the 'attractions' , but there is plenty to do, great restaurants, bars, museums, etc. Some of the towns in Washington County to the west of Todd Mission are fun. Have to eat some Texas BBQ and TexMex. All depends on your interests. Or you could come down and we could drag the speakers into the yard and grill some burgers!
