How big is the trading hobby?

Trading is totally addicting. I'm over 60 trades in 15 months.
A lot of others are apprehensive. My uncle in NJ and his buddies at work pay $35 on ebay for a sixer of Hopslam, and I yell at them. I will walk them through trading any time they want.
Fedex has NEVER asked what is in my box (because I walk in with a pre-printed label), but it is not that hard.
And an odd side reflection, I have made more solid, true friendships the past 2 years through beer tasting/sharing/trading than in other areas of my life. The beer community is an amazing and generous bunch of people, which I am happy and proud to be a part of.
Just my 2cents...
