There is a good group of people in the area who ride, probably 10+ (by area, I mean the DFW Metroplex), but depending on where in "Fort Worth" you live, our regular ride spot could be an hour away. Its still worth it IMO, I drive 45 min to get there, passing 2 other lakes.
@skinnyman lives closer to Dallas but has been riding here for a long time.
Fort Worth is a pretty nice place to live too. I'm not savy on lake front property value availability. I know that lake Granbury is getting sucked dry and its a bureaucratic mess. Lake Grapevine would probably the most choice place to live IMO because of the area, but I imagine its pricy because its smack in the middle of DFW.
I've only briefly lived out of state (WI) so I can't really comment on taxes. I know we don't pay a state income tax like most other states, but from what I hear you pay the piper with property tax and sales tax.
Coast trips happen occasionally. Its about 5-6 hours to Surfside Beach. Port A is closer to 7 hours.
I attached a little map to give you a lay of the land.
The star is our regular riding spot. Pretty much 3 weekends a month you'll find someone at Lake Lewisville, Spring though Fall. Sometimes every weekend.
The little Circle at the bottom is about where I live, just to show you my drive to the ride spot.
