In and Out today

I went over to the Rio around 11 am this morning to play in the donkfest that is the $1500 NL event. I got there and was surprised to find a line for this event, which is the first line I've had to stand in since Event #1. It moved quickly though and I was registered in about 20 minutes. There were so many people that my table was actually in the poker room, which is like a ten minute walk from the big main room. I estimated that there were close to 3000 people registered for this event, and by the time my table fills up, I have Mark Seif, Chip Jett, and some Asian guy who I know has been on tv and is solid at my table. This is really hard to believe that I got 3 known pros at my table in a 3000 person event, but what can you do. There were still some very obvious soft spots.
On the first hand, I look down a 77 and make a standard raise, and get called by a woman in the small blind who I know thinks she is good. The flop comes JJ5 and she checks to me and I bet 250. She check-raises to 625, and I made the mistake of just calling. It's a bad play to just call here, because you will face a larger turn bet about 95% of the time and my hand will only improve like 5% of the time. I should have either shoved on the flop or folded. I ended folding on the turn and cursing myself. So I'm down to about 2100 after this hand and I float around here for a couple of orbits. I then get Jh9h in the BB, and it folds to the button who makes it 150. I call and the flop comes 8910 rainbow, which is pretty solid for my hand. I check, intending to check raise, but the original raiser checks behind. The turn is another 9, giving me trips. I bet out 250 and he cold calls. Here I put him on a draw or one pair/two high cards. The river brings the Kc, which completes a backdoor flush draw. I bet 500 and he minraises to 1000, thus making me sick. I thought he might of backdoored me, but I call anyways. He ended up flopping the nuts with QJ and then I unfortunately hit that damn 9 on the turn making it too hard for me to fold. So no I'm left with less than 500 chips and blinds just went up to 50/100. I'm in the big blind with 4c5c and 4 people limp and small blind completes. The flop comes Q67 and I shove. The moron to my left thinks for awhile and cold calls with three people behind him still to act. One more guy calls and I have a chance to basically quadruple. The turn was 10, and the donk to my left bets out 1500 and gets the other guy to fold. He flips over 89 for a turned straight and I'm drawing dead. This play is horrible by him, as he most likely only has 6 clean outs in the majority of scenarios and still 3 more people behind him who could push him off the hand.
It's amazing how many people show up for these $1500 events and how awful about 98% of them play. You can literally look at person and tell they are dead money very easily. Oh, well. There are a few more of these type of tournaments, so if I can ever catch some cards and run well to build a stack early, the rest of the tournament should run pretty smoothly.
I did come back and started 4 tabling 2/4 and within two minutes, I stacked off to a guy who limped mid-position with AA and I had KK in the big blind. I will stack off there every time, and I took the immediate hit pretty well. I haven't been tilting really at all in this pretty long cold streak I have hit in the cash games. I just reloaded and played very well for about another hour and ended up +$150. I plan on quitting for the rest of the day because this will be my first positive session in about 7 days. I don't do this because I think the money is alot or anything, but I do think it helps with confidence, which is something I am beginning to realize is very important as a poker player. Hopefully, this will be a turning point and I can start building back up...
