Hey everyone, im brand new to these boards and was trying to find some info. I searched it and found that most people say it is fine to ride on the sidewalk.

I live in orange county, california and was wondeirng if it was legal to ride on the sidewalks here?
also, i was looking at getting a tarmac expert road bike to start commuting, right now i use my old mountian bike. is this a good idea? would it damage the bike to ride it on sidewalks at all? My commute is a 32 mile round trip and it just seems like having a road bike would make it so much easier!!!

Also, what are the chances of my bike being vandalized while in the employee parking lot, i've never heard of it happening where i work (very high end resort hotel) but im just wondering if anyone ever vandalizes bikes because they're pricey.

thanks for the help!!!
