Collant leak help

Apparently I have a coolant leak somewhere. I have checked for exhaust smoke at both idol and following behind my jeep, nothing. No coolant is hitting the ground at any point. I had to add almost a gallon yesterday and did so about a month or so ago also. I notice that my temp guage will move up and down more frequently when I needed to add coolant both times, but the temp never gets much over 210. Ocassionaly I will smell a small amount of coolant, but cant locate it anywhere. No water/coolant in the oil. Where could it be going? I have checked several times after running under the hood to listen and look for vapor to be coming out somewhere but to no avail. I haven't pressure tested it yet, but yesterday after cooling it down a bit, I slowly released the cap and there was alot of pressure and vapor evac. Any help would be greatly appreciated.

If you have an external leak you can't pinpoint, the best was is to have UV dye added to the system. Just about any garage/shop can do it. Then you come back in a couple days and they hit it with a black light and it is clear as day where it is. (if it is in the oil, the oil will glow also)
