If you're coming off of the parkway ... take hwy 55 thru Bloomfield & Wakefield, and turn right onto hwy 2239 and cross the dam. Go past the Marina ramp turnoff, and turn right onto hwy 44 at the gas station. Stay on hwy 44 until it turns into hwy 248 .. proceed on hwy 248 until you get to hwy 3230 (state park road). Possum Ridge ramp is at the end of this road, past the State Park building & the campground. (somebody correct me if these hwy #'s aren't right)
I drive there from Lexington, and it's about the same drive time - whether you go this route, or turn off at Lawrenceburg and come in from there ... about 1.5hrs for me (East Lex/Richmond Rd area).

map ... Possum Ridge Ramp is #3 :

Hope this helps, and doesn't confuse you more ..... I don't know anything about the tournies, so I can't help you there. And I haven't Bass fished T-ville in a couple of years, so I wouldn't be of any help there, either. ..... luck2ya ..... cp
