I dont mind temps in the 30s or 40s, but anything below 30 starts to bother me. But only if its like that continuously. If every 3 days is 20 degrees, then the next 3 its 30s or 40s, ill stick around. But if its like 20 degrees continously for a month ill leave, but i wont head to someplace warm, just someplace in the 40s or maybe 50s.
