Got this from another JEEP site.
Subject: You Know you're a wheeler when......
- You'll stop and look at any old rusty heap thinking "Parts Vehicle....."
- Your rig has more [farm/boat/military/other vehicle manufacturer] equipment on it than OEM parts
- The weatherman says "Stay in, it's dangerous" and you think "Time to go 'wheeling!"
- You're happy that you can't use 1st gear on the street.
- A military convoy passes by and you only look at the axles, tires and antennas
- You take your SO out to look at new home construction sites so you can drive on the unfinished roads.
- You have enough straps, chains, rope, etc. in your rig to keep the Queen Mary docked during a hurricane.
- You can break down on the road, diagnose/fix the problem, and get back on the road without calling AAA.
- You break down on the road, fix the problem, and get back on the road on a regular basis. 
- The AAA guy breaks down, you stop and fix his problem and get back on the road.
- You have a brand new set of tires, but you keep looking at the tire ads, anyway.
- You'll drive 2 days at 500 miles per day so you can spend 2 more days driving 3 miles per day.
- You get really steamed because you spent over an hour to go the 10 miles home from work on Friday, but are grinning ear to ear because you just spent 6 hours going 4 miles on your favorite trail on Saturday!
- Your CB has never been on Ch. 19, only Ch 4.
- You set up your rig to have a top speed of 65-70 mph - on purpose.
- When you pull up next to a Corvette, all the 'Vette driver can see is tires and whatever is on the other side of you.
- You challenge the 'Vette driver to a race... if you can pick the course.
- Author's contribution: You spend three hours mowing the lawn contemplating how your riding lawnmower would look/handle with 3" lifted 4 link coilover suspension, ATV tires and having the engine bored/honed/blueprinted/balanced ... does Jacobs make an ignition for Briggs and Stratton? what about a K&N air filter?
