15 gal hard rootbeer gone in 3 days, 5 gal hard cherry soda gone in 2 days and 5 gal hard lemon-lime soda gone in 4 days (held for special guests). Three Swans Inn, need to bring more rootbeer next year. Lots more.
I do a 2 week campout with my jockey box and kegs. I use 1 or 2 handels depending on the mixer. However i am pouring 100 gal over the 2 weeks and don't want to go broke. It tastes good and will get you a good buzz or maintain if you already have one. Hope this info doesn't come too late for you.
The fire extinguisher store in downtown mooresville fills them near the corner of nc 3 and Main st.
You can stop in at Beer Wine Hobbies International on 150 across from walmart while you are in the area.
