Rebecca, I remember a previous post that a visitor found storage at the bus station, so I called to see if still available, and it is. Lockers are $3 for the first hour and $1 per hour after that. It's difficult to find storage short term because of security/liability, esp. since 9/11. If you are staying at a hotel, they will often keep your luggage for you short term.
Sloping tops: while most lockers have flat tops, some manufacturers offer the option of sloping tops to their range of lockers. The slope may be of either 30 degrees or 45 degrees to the horizontal, sloping towards the front, and the purpose of this is to make it impossible to store items on top of the lockers, or to make it harder for dust or other debris to accumulate there. This is an important factor in places like food-processing factories or restaurants where hygiene requirements must be met. Locker CO
I agree with the suggestion about shipping your skis and boots, especially if you are not going to be using them after the Vail portion of your trip. Are you staying in LA for awhile or just making a connection there? If you are staying at a hotel in LA perhaps you could talk to them about having your equipment shipped there and stored as most hotels do have some sort of luggage storage facility. Hikers on the Appalachian Trail often ship supplies to US post offices that are in towns easily accessible to the trail so they don't have to carry everything with them. A lot will depend on your actual itinerary and whether you are stopping over in LA or just making a connection. You'll likely need to do some research and maybe think outside the box. I know it's always much nicer to ski on equipment you are used to but renting might end up being your best bet and the least hassle.
Perforated lockers are similar to the standard types of locker, but the door and walls are made largely or entirely of perforated steel, with hundreds of holes creating a strong mesh arranged in a diagonal pattern. This is used where good ventilation is required, or where, for security reasons, it is necessary that the contents can be examined visually while the doors are locked. School Locker
Worse company I've encounter, owner is a racist he's stuck in the 1950 way of life and the daughter & husband smoke more cigarettes than and testing tube in a tobacco facility. Service sucks they have one poor individual working the entire warehouse and refuse to hire more help. They don't provide benefits and expect the worker to work like a slave with no sick days off.
