i have 100 postcards ready to go to the post office. they are aimed at picking up mowing clients. our schedules are nearly full, we are looking to tighten our routes, and replace lower paying customers with higher paying ones. about a week and a half ago, the temp around here hit 60 degrees one day. since then i have been watching the forecast, waiting for a couple of forecasted nice days in a row, maybe mid 50's to 60, to send out the postcards. well that hasn't happened yet. in fact, most days have been overcast and cold, often with showers, and the 7-day doesn't look any better, messy next few days, and daytime in the 40's with temps in 20's and low 30's overnight for monday and tuesday. should i go ahead and mail them, or wait for the better weather?
