My bike is broken

Yesterday I got home a little after 7pm and my first instinct was to get on my bike and ride a few miles, since on wednesday (today) had to go to work for just a few hours, being my day off, I was not going to be able to ride early. Well, that didn't go too well. The rear sproket came loose and in the middle of the street over by the Pearl Brewery it just would not shift gears. I stopped and tried to fix it but to no avail, resigned I walked all the way back to my car, which was by the MUnicipal Golf Course.

From here, my agenda calls for getting some breakfast before heading to check out the pickup trucks that Jesus is interested in;

1. 1.- At 12179 FM 1518 North, Cibolo, Tx. 1997 Chevy Silverado 1500 Z71, 166K $4,500 maroon.Carfax shows one owner. $208 under value.
2.  8903 Grissom Rd.- 2002 GMC Sierra Z71, has 204K miles , is maroon. Apparently driver's side wheel bearing needs service/replacement. Carfax shows one owner. $1080 over value.

Next , I need to see if I can fix my bike by myself or maybe I will take it to a bike shop if is not too expensive to do so, keeping in mind that two weeks ago I spend $75 just to get a new tire, tube and protective liner for the rear wheel, that was almost half the price of the bike.
If all goes well, I will go for a long ride, to make up for the time lost.
Laters. and let's roll!
