To get to HP from Boston, take 90 West for about 30 miles to exit 11 which is the 495 junction.

Then take 495N for approximately 4 miles to exit 23C which is called Simarano Drive.

Then follow the instructions below.

Off of the exit head right. You will get to a light. Take a right here as well.

When you are on Simarano you will go about .25 miles and then look for a right turn. Note that it is marked "Fidelity" and NOT HP.

After the right, you will deadend into a T. Go left on Puritan drive (note you are now on the Fidelity/HP campus).

Head past 4 speed bumps up Puritan Drive. You are going to go to a stop sign (see below).

At the stop light, you are looking at the main HP building. Make a right and look to park in the parking lot that is on the left.

To get into the parking lot, take a left turn up what looks like a short 1-way street.

On the side of the parking lot, you will see a helipad with two helicopter landing pads and a small brown shed. Wait here and call up for someone to come get you. Note that this is a backdoor to the building so there will be no lobby or security to let you in (you must wait for an HP badged employee)
