What motivates the choice? My practice is to leave the wraps on as long as I can. Normally I will unwrap and close the top entrance between April 15 and May 7 (more or less). This choice of closing the enrance is motivated by my need to see what is going on and what my winter losses have been. It may be better to leave the upper entrance or even re-wrap but my management in this case is dictated by my laziness. Eric Abell email: [log in to unmask] Gibbons, AB, T0A 1N0 Canada (403) 998 3143
