The good, the bad and the ugly..
/Good:
Ice cream stands
Farmers markets, especially those with ice cream (see above)
Rail trails
Geoff giving me a ride instead of just passing by waving and bringing ice cold beverages. I know its "cheating" but I was tired and you know you would do it too, especially when you saw the hills.
Bad:
0-10 miles: Steep and/or really long hills
10-20 miles: Most hills
20+ miles: Anything resembling a hill
Complete lack of street signs
Having the wrong address for the destination
Ugly:
Gravel trucks
