Hi everyone! I'm brand new to cycling and this board. I have several questions. First off, for those that don't know, Tahoe where I live, is VERY mountainous, and in the town I live in, very hard to find flats. Should I just ride that flat (6 miles round trip) over and over again until I get better, or are hills OK?

Secondly...as I"ve seen many people mention, my butt HURTS! I am extremely (read super fat) out of shape, but do have a good mountain bike (a GT Aggressor that is a couple years old but freshly tuned). I put semi slicks on it, and have a cutout gel seat, but after just a couple mile ride today.. my butt is killing me. I don't have the money to buy the chamois from this website right now and plus size stuff is just not sold in normal bike shops, especially in the tiny town I live in. So, because it hurts so much, should I suck it up and ride again tomorrow? Or wait a day and let the poor rump have a break?

Lastly...anyone nearby?

Thanks in advance for all your help!
