This summer im going up to virginia. My dad use to catch smallmouth in creeks , he said he used rubber worms. wht would be the best way to catch smallmouth in creeks. also what would be the best way to catchem in lakes.

I'd start out with some baits that will for sure catch fish (quantity), then branch out from there and start focusing on quality. Here are my suggestions for quantity:

-3'' or so grubs on 1/8 oz jighead...med/slow retrieve

-small crankbaits (shad or crawdad colored)

-soft jerkbaits/sticks like a fluke or senko

-small topwaters - torpedo, buzzbaits

That should do the trick on a lake or river. In the lakes you may have to focus on deeper water if its summertime.  Also tubes are crucial, but are an aquired taste and can be frustrating at first (snags a plenty!)....work like a charm though  

Good Luck!

dependin your fishing prefence(alot of small fish or few monsters) i would say to target quick dropping shorelines and fish what ever deep visible structure u can find to catch them. i like to use 1/16 weedless jigheads with a green plumpkin 3 inch senko on it and just bounce it around the deep structure. You be sure to hook into a few smallmouth by doing this.
