As a solo or small gang PVPer (or even a roaming alliance) you crave more fights. This can be difficult if you limit your self to one area of the EVE Universe because conflict in EVE moves from region to region on a weekly basis almost.
Not long ago we had "Content Ring" the nickname for Cloud Ring after the Sov Changes lured countless alliances to claim their little piece of space only to find out it's not worth holding. During this time there were large scale mega battles and small scale brawls. But it all dried up for the most part as everyone decided they didn't really want Sov and that the new system just wasn't very fun.
At this moment the busiest place to be is Querious as a result of all the large new player groups moving there (Horde, Brave, Northern Army). More people close to each other equals more conflict and leads to more fun.
But this too will pass and depending on the tides of EVE could move to Providence, or Pure Blind, or Delve, or even back to Cloud Ring.
What you need is a way to know first what region to look in, and next what systems to look in.
To find the busiest region, your best bet is Dot-Lan and it's statistics page.
The top 24 hour statistic is your best bet, however the second statistic that shows 3h and specific system is a great place to find where recent battles have occurred which offers both PVP and ISK making opportunities.
Once you are in the region you need a more real time (delayed 5-15 minutes I think) method of finding people. This can be done in Dot-Lan but I prefer to use the EVE Map from in game.
Once you open the map you can find the statistics section like this:
My default setting is "Average Pilots in Space in the last 30 Minutes" because I find this to be the most reliable indicator. For Querious you can see the entrance system is busy:
The next stat of interest that further indicates this activity is PVP and not mining or ratting is the "Ships Destroyed in the Last Hour" stat:
This tells me there is definitely something here worth investigating. It could be a bubble camp or it could be two groups skirmishing or maybe something else like a timer fight.
Another great tool for finding fights and seeing what ship types and fleets are around is by using ZKillboards Regional killboard for Querious.
Finally, if you would like to work the edges and have a better chance of avoiding the blobs, you could always analyze the traffic patterns of the area and setup your own little bubble camp nearby:
This system is only a few jumps away and shows alot of traffic. Many times this traffic is disorganized and offers you some good opportunities.
The more information you have the better your results will be.
