I moved specifics about
GMRS radios to clean up the main post (which links here):
- Models range from 1 watt to 2 watts (usually, moar = better)
- Technically, you're supposed to get an FCC license to operate GMRS, but you can still buy a radio without one and they're backwards compatible with FRS (0.5 watts)
- These are widely available at Best Buy, Walmart, Amazon, etc
- A headset might be a good idea too
- If you don't bring a radio, no worries... it's not required for the drive (it's just a suggestion)
