I live in the northeast US and have a depression in my backyard: after weeks of freezing weather we had a warm, rainy weekend. Then it all froze =)
So now I have a backyard rink, about 100' x 50' (30m x 15m), but I'd like to get it flatter and better-suited to skating. There are spots where it was slushy and a bootprint froze in, ridges and ripples from who-knows-what, &c.
I'm willing to build apparatus to help me, but would rather not spend much. (Say, under $100 US.) I'm willing to spend up to an hour a day out there working to maintain the rink.
I'm not willing to just flood it to a depth of two inches to set a new layer: that'd take way too much water.* I want to use the existing ice (and surrounding snow, if more water's needed) as much as possible.
How can I perfect this rink and ensure my kids the best skating every afternoon, all winter?
* - I know because two years ago, last time this happened, I tried just flooding it. There's enough topography to the ice that In a month of late-night floodings I wasn't able to raise the level enough to effect changes to imperfections on the not-level portions.
