I agree. I can spend 3, 4, 5 hours a day on it for 3, 4 or 5 days, take a break for a week or 10 days and then do it all over again. :~) It may be taking me longer because I'm not paying for a membership, but I find it fun, with the various tricks I've discovered to find info I rarely get stuck for long and there are only a couple of mystery people still on my list.
I’ve found lots of interesting facts about my family, but I think the one that amazed me the most was finding on the net a painting of my gggrandfather that fought in the Civil War and who was captured (luckily) the 1st day of battle at Gettysburg who bears a striking resemblance to my own son.
It’s those kinds of finds that makes the search both enjoyable and worthwhile!
Happy ancestor hunting!
