we just moved to Castle Rock Co. a month ago from Seattle and were lucky to find a house (according to the locals),market is berserk here and they are building everywhere around us like crazy ,with projections of crazy prices just going higher due to lack of supply, seems to be a popular place to be moving to right now.
anyway we brought all our homebrew supplies down and have brewed our second batch already and have taken a class at the local homebrew supply here in town which as always is very helpfully . they do mention the moderately hard water and having to deal with it (filters and adding gypsum) and how it can fluctuate due to using various wells to supply the systems, its easily dealt with . our house was plumbed for natural gas and when we went to purchase a new BBQ we mentioned using NG instead of propane and were warned that due to altitude (6250ft) the NG wouldnt work as well (less BTU's) ,we converted anyway and find the BBQ works just fine . so will try to convert my brew kettle burner to NG for an upcoming brew session and see how well it works (just another thing to think about ,i know we didnt), i like the idea of not having to keep purchasing propane bottles...
the basement (with floating floor?) seems to be working well to keep carboys in the 63-68 deg range during fermentation (though we are having a mild summer so far according to the locals, only a few days above 90) ,i do open windows in early AM to bring room temp down to 65-68ish and it doesnt rise much during the day (nice thing about here is it does cool off overnite). house has a nice covered patio to BBQ/brew under though its often quite windy (usually about the time i fire up to brew) and almost every day around 4pm a thunderstorm rolls thru ,so you definately want a covered/sheltered area if your brewing outside
