If you are kegging and have a second keg, it's awesomely simple to dry hop in the keg. Best to bag your hops here, and tether them to the beverage out post or clamp it about halfway up with a food safe clip.
Aside: why does every time I type kegging it corrects to legging? what the hell is legging anyway ? Legging out a bunt ? Goat leggings?
