Charles, I would highly suggest getting a used bike, as there's plenty of great bikes to be had on Craigslist etc. I got my amazing Kona AA used. If you are only considering something new, I would choose the Giant Revel 1 over the Roam (if you want suspension).

Honestly, a bike with suspension is overkill if you're going to be riding on paved trails. Unless you lock out (as you should) the suspension (which you're paying extra for), it's actually a more difficult ride. I know a bike with suspension looks more "cool", but it's really not practical at all for the terrain you'll be riding.

I would take a serious look at a rigid frame new or used bike.

The only reasonable argument for owning a gun is to protect yourself from the police.
