If you want to get really creative you can do a few things:
1) Fully wipe the bike down before you bring the bike in so that there's not a trail of snow and mud
2) Get those hooks from performance and install it on the wall or get a big bike hook from Lowes or Home Depot that you can install in the ceiling and hang your bike from. Do it in a corner of your office that gets no use or traffic.
3) Get one of those curtain rods and extend it from the wall out to about 3- 4 feet. Then go to Sears and get some curtains and use it to cover the bike when it's hanging.
You're an engineer. You can build it. If you build it, they will come (or not come for the bike and conficate it to the outdoors).
