I wouldn't worry at all. You got to hang stands at sometime and right now is as good as any. The farmers are all out planting so deer are seeing people out on their turf. Plus, with the spring weather, the rain will wash away your scent. I hung one batch of stands about a month ago and the rest of my new ones will be going up in Mid june. Gives them plenty of time to get used to them. I also like to get any major trimming that I have to do done now. Then when August rolls around I check for any small summer growth that will effect my shots. I also like to make sure I get my gear rope and gear hooks out this time of year. Then when i double check stands in August, I get in and get out.
