carry mine in one of my pocket jersey's as well as my cell phone.
I take my epi kit with me rather hot or cold weather.

MS 150 ride in June I got stung 3 times in the neck, stopped used my epi-kit popped the needle into my quad, ride marshall's stopped called the paramedics, checked me out and said I should wait or not ride.
Anyway went and finished the ride but @ 3 of the rest area's/stops the paramedics were looking for me and I stopped to let them check me out..
Finished the ride with no side-effects even though the ride was a lot slower than I anticipated
