Ok, now that I have your attention! Ok, possibly just yellow jackets
Beware that there is a large grapefruit sized hornets nest on the McIntosh Run bridge by Pizza Corner. It is located under the centre siderail truss at the highpoint of the bridge.
Since it’s very common to stop on the bridge to regroup you will encounter them if you do so.
Next time I’m there solo I’ll knock it off and hammer outta there if it’s still there but ideally someone with a bugsuit could get 'er done.
