Being a human map, there are 4 - 5 areas that are Hobby central
Galleria area (610-Westhiemer zone) This area has alot to offer, both in hotels, clients etc..
I-10 and beltway area (this would include the beltway and Westhiemer area) both areas are full of hotels, one is Westchase area (beltway 8 and Westhiemer) and the other is near the Energy corridor (I-10 and Beltway 8)
I 45 north and 1960 area. This zone is full of Hotels, but be warned that up and down 1960 are alot of AMPs/ Spas so for an independent you need to be careful.
45 south near Beltway 8 not as popular as 45 north area but it has its share of ladies.
59 south / southwest alot of ladies post for this area... and it is also full of adult clubs etc...
For me, my favorite area of town matters not... I know the town, have seen ladies from Stafford area to 59 north and 1960...
As for what area of the body parts...well when I meet the lady it can vary... but lets just say "I loves da ladies "
