I've got a great map from the Boise Chamber of Commerce I can mail you. It's very detailed and easy to read. LVGAZ makes some good suggestions. You need to get downtown and experience the people, food, shops etc. Look at the thread Fall for Boise is almost here. There's a couple of links there that might give you some things to do. There's also a trolley that you can take that gives you a tour of the downtown area. Try this number:
Boise Tour 208- 433-0849
They just went through a change of ownership and I'm not sure if they are up and running again or if this number works, but it would give you some insight into the city and add to your experience.
You can also take a drive up Bogus Basin Rd at dusk and have many views of the city lights. Or if you want to head up further into the mountains take hwy 55 to McCall, about 2.5 hours away and check out the Payette Lake. Beautiful drive! On your way you can take a side trip to Tamarack to view the country's newest ski resort. It's a work in progress, but as you drive through it you will be impressed with the structures and atmosphere that is being created up there. If you have a chance go to the real estate office and look at the model replication of what it will look like when it's complete. It's going to be an amazing little town of it's own. I'm guessing on the miles here, but I believe it's about 10 miles off of Hwy 55. As you're driving north on 55, the road that turns to take you there is in the small town of Donnelly. Watch for the green signs that direct you to Tamarack. There's a map on the website below and also written directions. Look under Getting Here on the left hand side of the web page.

As far as subdivisions to visit, there are tons. It's difficult to direct you to any specific one without knowing what your needs are. If you want to see some historical homes drive down Warm Springs Ave like LVGAZ said and also Harrison Blvd.
Click on my name and send me a direct message with your address and I can mail you a map. If you want to give me more details about what you might be interested in for a home I can be more specific of different areas to look at.
You're going to have a great time!
