Tampa Bay is a large area. Do you work from home, or commute to an office job? What hours are you able to ride? This will be a big factor. Similar to the bay area, our area is spread out and can have a 1.5 to 2 hour drive between locations even in optimal traffic conditions.
Bayshore Stables is closer to Tampa. Derek Van der burg is the trainer there. From what I see on their page, they seem to have a focus on jumpers. They do a lot of rated shows, and you can check them out on instagram and FB. When I was looking for board a few months ago, they did not yet have lights for their arena but were planning on it.
Premier Show Stables is in the Riverview area of Hillsborough County, a little north east of you. Not sure how many A rated shows they do, and I don’t know much about their trainer. But the facility appears nice and they have lights if you need to ride in the evenings. That area does suffer from terrible traffic, though.
As someone said, Sarasota/Bradenton/Parish may be a good option because Apollo Beach is not too far north. It would also put you closer to Terranova and Venice , so less of a haul for rated showing.
