I grew up in North Ogden, so I believe it is called the Pleasant View exit, but I can't remember the number. I'm sure I can find it on a map later today. There is a Large Maverik Gas Station, Mcdonalds, and Mexican restaurant at that exit.
*Edit
OK I found it....I-15 EXIT 352 onto State HWY 134 Farr West North Ogden. The sign should say either N. Ogden or Pleasant View...they may have changed it. Here are the directions from Salt Lake City to the exit you want. Cut and paste this link:

[moderator advise] it'll be easier to use shorter version of the link - just copy this one
