HOU is a lot friendlier to GA than IAH... You'll be flying the pattern
with 737s, but you'll be probably landing on the shorter parallel
runway (12L instead of 12R)... Depending upon where you're coming from,
you can a lot of times just call up HOU tower instead of Approach
Control and not get routed all over everywhere... Houston has a lot of
smaller airports, so finding one fairly close to where you want to go
should not be that difficult... Houston does have a serious rush hour
traffic problem, so you might want to consider that depending upon the
time of day...
