PROBLEM: Review: This book outlines hundreds of different routes up all of the Wind's well-known peaks (as well as several not-so-well-know ones). He did a phenomenal job amassing all of this information. There is enough here for a short lifetime of awesome mountain trekking.The information Kelsey gives is mean, lean, and straight to the point. Novices beware, this book makes no attempts to come down to anyone's level. It is written for those grounded in that arts of route-finding, technical climbing, and alpine survival. It is not a hiking book. If you are uncomfortable with this, either buy a more toned-down Wind River guide, or pick up a book to build your skills like "Mountaineering: The Freedom of the Hills" and start psyching yourself up for some world class backcountry.

PROBLEM: Review: I bought this for my 4 year old daughter for her birthday. She loves rockets and I thought she would enjoy it. The pump is total junk and could not even pump enough pressure for a single flight before it broke. I spent an hour trying to fix it and the highest I've gotten the rocket to launch is a couple feet! This resulted in my daughter crying and the rocket getting thrown away. Do not buy this one!
