Okay, since we have a lot of new HR MINI members that have joined lately, it might be worth mentioning some basicals about our runs.
When we have our group runs, or join other clubs in their runs, we stay in contact with each other by using FRS radios. If you don't have radios, you're just following the MINI in front of you. However, if you do have "ears" you can join in on the fun and stay abreast of things going on or last minute agenda changes.
These are the ones I use and I've been very happy with them. In fact since one got damaged and I was down to one, I ordered another set from Amazon. Great price and I got them in 4 days. I'd highly suggest these, but there are a LOT of choices out there.
Here's mine:
