I will be driving to Boise ID. the last week of Aug. first week of Sept. to visit my sister that doesn't fish. She is no help.
My history is in fished spring creeks with small flys. My rods are a 3 and a 5 weight.
I would like to try something different.
The advice i'm looking for is;

1.Who or what local shop should I try to contact when I get there?

2.Other than the boise river in town, where should I try fishing?

3.What flys and size should I tie to take with me?

Thank you in advance for any advice.
